(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)This thesis presents the work done on the design of a low voltage high performance, wide bandwidth current feedback amplifier [CFA] with complementary input pair. The design is carried out in 1.8 V, 0.18 micron CMOS process. ... -
Design of the high speed, high accuracy and low power current comparators
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Comparators are non linear, decision making analog circuits, which find wide spread application in data converters, data transmission and others. Comparison can be done in terms of “Voltage” or “Current”. A current ... -
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 ... -
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 ... -
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. ... -
High speed, low offset voltage cmos comparator
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)The Analog to digital converters are the key interface blocks between the continuous time domain and the discrete-time digital domain. The performance of high-speed data conversion and digital communication interfaces is ... -
High-performance low-voltage current mirror design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Design of high precision analog circuits requires accounting for the mismatch between nominally identical transistors. In this work, errors affecting CMOS current mirrors due to mismatch between identical transistors are ... -
Low power high speed amplifier design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)The operational amplifier (op-amp) is one of the important component in analog to digital converters. The power consumption of these converters mostly depend on the op-amps used. The accuracy and speed performance of analog ... -
Test methodology for prediction of analog performance parameters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Analog testing, the name itself signifies the detection of faults in analog circuits. The aim of this thesis is to increase the test effectiveness and work in the performance parameter space. There are many test methodologies ...
