Analog Silicon provides Analog & Mixed Signal transistor level IC design on CMOS & Bipolar processes. Analog IC design is performed using SPICE with a strong emphasis on IC layout & geometric considerations for analog performance and management of parasitics' effect on performance through back-annotation. Test mode observeability of analog performance is implemented for both characterization and production test.
