Abstract

An RF MOS transistor having improved AC output conductance and AC output capacitance includes parallel interdigitated source and drain regions separated by channel regions and overlying gates. Grounded tap regions contacting an underlying well are placed contiguous to source regions and reduce distributed backgate resistance, lower backgate channel modulation, and lower output conductance.
