1. A metal-oxide-semiconductor field-effect transistor (MOSFET) circuit fabricated on a silicon substrate, comprising:

  • first circuitry implemented using current-controlled complementary metal-oxide semiconductor C3MOS logic wherein logic levels are signaled by current steering in one of two or more branches in response to differential input signals, the first circuitry being configured to process a first signal having a first frequency; and

    second circuitry implemented using conventional complementary metal-oxide-semiconductor (CMOS) logic wherein substantially zero static current is dissipated, the second circuitry being coupled to the first circuitry and configured to process a second signal having a second frequency that is different than the first frequency, wherein the first circuitry comprises an input circuit that is implemented using the C3MOS logic, and is configured to deserialize the first signal into a plurality of lower frequency signals.
