ABSTRACT:
Channel coupled feedback- technology for implementing many analog and digital signal processing functions in a single-polysilicon digital IC fabrication process is described. Field effect transistors are constructed having a common channel and the substrate regions of the field effect transistors in the channel are electronically connected. Thus, a fixed amount of charge can freely move within the channel in response to the application of the signal to be processed. By sensing the charge transferred within the channel when the input signal is applied, many signal processing functions are possible. Fixed-gain amplifiers, offset compensated amplifiers, integrators, differentiators, analog-to-digital converters, digital-to-analog converters, switchable gain amplifiers, automatic gain control systems, and linear transform computation circuits are constructed entirely with field effect transistors, eliminating the need for passive components for most signal processing functions.
