CMRR-bandwidth extension technique for CMOS differential amplifiers

Bandwidth Extension for Transimpedance Amplifiers

This chapter aims to introduce optical receivers in general and application of electronic circuits in these receivers then some important parts of these electronic circuits which are the amplifiers are discussed. An attempt has been made in this chapter to provide some useful information about different aspects of the optical communication in our life and the importance of high speed wideband a...

Multi-Pole Bandwidth Enhancement Technique for Transimpedance Amplifiers

A new technique for bandwidth enhancement of amplifiers is developed. Adding several passive networks, which can be designed independently, enables the control of transfer function and frequency response behavior. Parasitic capacitances of cascaded gain stages are isolated from each other and absorbed into passive networks. A simplified design procedure, using well-known filter component values...

Characterization of CMOS Fully Differential Amplifiers for Automatic Design Procedure

This paper presents the design and characterization of fully differential amplifiers for application in an automatic circuit sizing tool. The tool uses Simulated Annealing as main optimization heuristic and electrical simulations for circuit specifications evaluations. The methodology is based on the minimization of a cost function and a set of constraints in order to size each transistor of th...

Fully Differential mm/sub-mm Wave CMOS Amplifiers

This paper presents an effective design methodology and flow, which is validated through three mmwave/sub-mm-wave amplifiers: including W-band LNA with NF=7dB, W-band PA with PAE >11% and D-band amplifier with gain>20dB. The CMOS based amplifiers can be integrated with III-V materials to form heterogeneous integration, such as COSMOS, to achieve the best performance for various applications.
