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 ...
Bidding strategies for dynamic spectrum allocation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Dynamic Spectrum Allocation is the process of assigning spectrum licenses in terms of the chunks of the spectrum band to the Wireless Service Providers (WSPs). This allocation assignment is being done as per the WSPs' ...
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 ...

(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. ...
Low power SAR ADC with split capacitor DAC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Analog to Digital convertor and Digital to Analog convertors plays a vital role in Mixed Signal Design. Nowadays, the demand for designing of Low power, Moderate Resolution ADCs are increasing for Bio-medical applications ...
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 ...
