Abstract: A precision SET-RESET logic circuit and operating method separate a latch function from the critical signal path which produces the logic outputs. In a particular implementation the logic circuit includes two differential switch pairs controlled respectively by SET and RESET inputs, with respective enable circuits for the differential pair controlled by the output of the latch circuit. The SET and RESET differential switch pairs respond faster than the latch circuit to a change to the input SET-RESET state. A logic output is initially produced by establishing a first current path through. the differential switches and enable circuits in response to a new logic input, and then latched via a different current path.

Abstract: A parasitic capacitance cancellation circuit for a direct bonded silicon-on-insulator integrated circuit includes one or more transistors fabricated silicon-on-insulator; a silicon substrate region outside the transistor(s) having a parasitic capacitance to be cancelled; a bootstrap terminal connected to the region outside the transistor(s); and a unity gain buffer responsive to the output of the transistor(s) and having its output connected to the bootstrap terminals for providing a voltage to the region outside the transistor(s) which follows the voltage developed on the parasitic capacitance and nullifies the parasitic capacitance.
