Abstract :
The results of a VLSI implementation of CMOS custom integrated circuit featuring high performance programmable switched capacitor analog building blocks is presented. The networks realized are based on the composite op amps, previously introduced and known for their extended bandwidth and reduced active and passive sensitivities. For proof of concept, a CMOS chip was designed and manufactured featuring two different SC composite op amps, and based on a stray insensitive design. Experimental results of the 40 pin prototype chips verified the design concept that was demonstrated theoretically and using SPICE simulation. The results clearly demonstrate the enhanced characteristics of these family of composite op amps when utilized in different applications
