Title: A 90 dB, 85 MHz operational transconductance amplifier (OTA) using gain boosting technique
Author: Vora, Ashish
Abstract: Gain and speed are the two most important parameters of an amplifier. Optimizing an amplifier for both of these parameters leads to contradicting demands. Various architectures have been reported to obtain high gain from the circuits. Cascode circuits are widely used in circuit design at places where high gain and high output impedances are required. Different architectures like triple cascode topology, dynamic biasing and a positive feedback amplifier have been used to obtain high gains. These architectures have been compared in this thesis along with drawbacks and advantages of each.
