Abstract:
A method for estimating performance of a circuit that includes a semiconductor device, the semiconductor device comprising a semiconductor junction, the method comprising the steps of:selecting a model for the semiconductor junction from one of a plurality of semiconductor junction models to identify a probability of charge distributed across the selected semiconductor junction, the probability of charge being a function of a junction voltage (V.sub.j) across the selected semiconductor junction;representing the semiconductor junction as a junction capacitance (C.sub.j) in parallel with a junction resistance (R.sub.j);calculating the junction capacitance based on said probability of charge for said selected semiconductor junction, said junction capacitance being a function of the junction voltage (V.sub.j) across the selected semiconductor junction; andusing the junction capacitance in a circuit simulation tool to produce an output performance of the circuit.
