Short description

Integrated Circuit Design for a Frequency Synthesizer Phased-Locked-Loop (PLL) at 24 GHz

Motivation:

Phased-Locked-Loops (PLLs) are commonly used in integrated circuits (ICs) for frequency synthesis. A locally generated high-frequency clock or carrier signal is synchronized (typically) with a low frequency and low jitter reference signal to improve its jitter characteristics and process-voltage-temperature (PVT) variationtolerance. The main circuit components of a frequency synthesizer PLL are as follows:

phase and frequency detector (PFD), charge pump (CP), loop filter (LF), voltage controlled oscillator (VCO), frequency divider (1:N) and pre scalar (1:P). Each participant of the project will design an individual circuit component of the PLL. The design of the component will include schematic design and simulations as well as circuit layout using tools from Cadence Design System. The target semiconductor technology is the 65 nm CMOS technology from TSMC.

Tasks:

  • Learn to use modern industry standard IC design software
  • Develop a circuit from schematic to layout in a modern CMOS technology from a commercial foundry
  • Cooperate with other students in the team to define and design circuit interfaces
  • Present results in review meetings and to document them in the form or a written report

Requirements:

Participation in one of the following lecture courses is considered mandatory for participation in this project:

  • „Schaltungstechnik“ from „Bachelor Electrical Engineering“ program of University of Paderborn.
  • "Circuit and System Design“ from „Electrical Systems Engineering“ or “Computer Engineering” programs of University of Paderborn.
  • Other relevant and comparable circuit design oriented lecture courses from another university.

Visible light communication

Introduction:

Lightning bulbs will be replaced by LEDs as main lightning source for indoor and outdoor environment in the next years. Beyond their ability as light source, LEDs can be used for the application of Visible Light Communication (VLC).

VLC offer several THz license free bandwidth in the electromagnetic spectrum. In comparison to RF based technologies, VLC have a high directivity. This allows spatial reuse of the Bandwidth.

This makes VLC attractive for many applications. One of these applications is VLC in the automotive area. Our approach use an off-the-shelf LED headlights and taillights. With little changes, this hardware can be used for Mb/s VLC.

In the next winter semester, the project group will design among others, an integrated receiver Chip. This consist a transimpedance amplifier, a low noise amplifier and a output buffer. The students will work with modern chip design software.

Tasks

  • Learn to use modern industry standard IC design software.
  • Develop a circuit from schematic to layout in a modern BiCMOS technology from a commercial foundry.
  • Cooperate with other students in the team to define and design circuit interfaces.
  • Present results in review meetings and to document them in the form or a written report.

Prerequisites

Participation in one of the following lecture courses is considered mandatory for participation in this project:

  •  „Circuit and System Design”
  • “Fast Integrated Circuits for Wireless Communications”
  • “Wireless Communication”, would be nice but not necessary

WS Applied programming

Course No.: L.048.10502

Contact: Dr. Wolfgang Müller

Type: 2P

Credits: 2

Semester: Wintersemester

Schedule and Location:

Block course, t.b.a., whole-time


Abstract

In this course the learned knowledge about programming with C / C ++ given in the lecture data processing is practically applied and demonstrated with a software application based on a practical task in small groups under the guidance of tutors. The course is offered as a block course and carried out by several departments of the institute of electrical engineering at the same time with different tasks. The current dates will be announced in PAUL.

The assignment is done through a written project report.

Short description:

IC Design for a 24 GHz Pulse Doppler Radar for Automotive Applications

Motivation

Radar Systems are commonly used in modern Systems. Since many years the automotive industry uses 24 GHz Radar Systems e.g. as reverse Warner. In Comparison to ultrasonic ‘Radar’ 24 GHz Radar signals have a lower response time due to the high velocity of the electromagnetic waves in the air. Further it allows due to integrat the full system on on chip (SoC). The main circuit components of a 24 GHz Pulse Doppler Radar are as follows: Phased‐Locked‐Loop (PLL), Power Amplifier (PA) , Transmit Antenna (TX‐Ant), Receive Antenna (RX‐Ant), Low Noise Amplifier (LNA) and Quadrature Mixer (IQ‐Mix). Each participant of the project will design an individual circuit component of the Radar. The design of the component will include schematic design and simulations as well as circuit layout using different CAD Software.

Tasks

  • Learn to use modern industry standard IC design software
  • Develop a circuit from schematic to layout in a modern CMOS technology from a commercial foundry
  • Cooperate with other students in the team to define and design circuit interfaces
  • Present results in review meetings and to document them in the form or a written report

Requirements

Participation in one of the following lecture courses is considered mandatory for participation in this project:

  • Lecture ‘Circuit and System Design’
  • Lecture ‘Fast integrated Circuits for Wireless Communication’
  • Lecture ‘Introduction to High Frequency Electronics’ would be fine but is not necessary
  • Other relevant and comparable circuit design oriented lecture courses from another university.
