The Design, Simulation, and Fabrication of a BiCMOS VLSI Digitally Programmable GIC Filter

Abstract

This thesis used a previously-designed programmable GIC filter as a basis in which to incorporate a BiCMOS operational amplifier. An NPN bipolar transistor layout was designed and incorporated into an opamp layout which was a modified version of a CMOS-only design. The BiCMOS opamp was simulated using Silvaco SmartSpice and showed considerable improvement over its CMOS equivalent. Additional improvements were made to the GIC filter to include a passgate with reduced resistance and a correction was made to the capacitor layout. Simulations were also performed on a switched-capacitor bilinear resistor and a switched-capacitor variable bilinear resistor. Results from the bilinear resistor simulations require further study and testing. Finally a VLSI layout of the filter was accomplished using LASI and has been submitted to MOSIS for fabrication.
