Generation of Programmable Composite Operational Amplifiers with a CMOS Integrated Circuit

Abstract

A general approach for extending the useful operating frequencies of linear active networks is the Composite Operational Amplifier. The Composite Operational Amplifier is generated by replacing single operational amplifiers with a network of N operational amplifiers (CNOA). This novel approach is extended to the integrated circuit. Three, 2 operational amplifier (C20A), composite forms are integrated on to a single chip. Additionally, the resistor network of the composite is constructed to be digitally programmable making the composite operational amplifiers capable of different Q factors. The chip is constructed with 200 transistors, four capacitors, and 10 resistors as major components. The overall size of the chip is 136 by 1285 mils and is packaged in a 24 pin dual in-line package (DIP). (Thesis).
