FM based pipeline ADC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
This thesis aims at designing a new architecture for an FM based pipelined Analog to Digital Converter (ADC). It is based on the fact that power is a function of voltage and therefore handling with voltage becomes a difficult ...
Design of low power and high speed decoder for 1MB memory
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Technology scaling is accompanied by rise in leakage power dissipation. This thesis proposes a voltage controllable circuit in the feedback path of the decoder, which drastically reduces the standby leakage current with ...
Extremely low voltage operational amplifier design with rail-to-rail input common mode range
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Increasing trends towards battery operated systems demand circuits to be designed at low voltages. Low voltage operation severely limits the operational amplifier as a voltage buffer as the input common mode range available ...
Design of multi-band fractal antenna for satellite navigation application
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Recent efforts by several researchers around the world to combine fractal geometry with electromagnetic theory have led to a plethora of new and innovative antenna designs. This research proposal has been primarily focused ...
Implementation of constant gm CMOS op-amp input stage using overlapping of transition region at 0.18 um technology
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Operational amplifier is the backbone of most of analog circuit design. For low voltage applications, op-amp should have a rail-to-rail common mode input voltage. This report describes the implementation of a constant gm ...
Statistical co-analysis, robust optimization and diagnosis of USB 2.0 system for signal and power integrity
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Signal Integrity (SI) and Power Integrity (PI) are the most critical issues as semiconductor industry is moving towards higher operational speeds. Signal integrity and power integrity are such issues that should be looked ...
Frequency compensation technique for low voltage three stage operational amplifier
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis presents a new frequency compensation technique for low supply voltage three-stage operational amplifier at higher loads. It is based on the miller splitting and pole-zero cancellation using feed-forward path. ...
Design of low-voltage, low-power, wide-band CMOS LC VCO using active inductors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In this thesis the design of low-voltage, low-power, wide-band CMOS LC VCO using active inductor has been proposed. The oscillator is based upon the classic LC-tuned negative-resistance topology, with a novel active inductor ...
Low power high slew-rate adaptive biasing circuit for CMOS amplifiers
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Adaptive biasing technique in analog and mixed signal integrated circuit design is used mainly to reduce the power and improve the driving capability. It has found many applications, like power amplifiers in RF communication ...
CMOS latched comparator design for analog to digital converters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Conventional comparators are at the two extremes as far as power delay product and isolation between input and output is concern. Either they achieved very good isolation at the cost of power in the preamplifier or save ...
