D-23,134 SIMULATION CIRCUIT EMPLOYING SWITCHED CAPACITORS by Man Shek Lee Abstract of Disclosure A circuit for simulating the parallel combination of a floating inductor and capacitor in the bilinear and LDI domains has a pair of nodes receiving an input voltage and connected to input terminals of associated first and second voltage followers. A first capacitor C1 is alternately or periodically connected across the output terminals of the voltage followers for sampling the input voltage, and connected between the output of the second voltage follower and the input terminal of an integrator including a second capacitor C2 which integrates and stores the charge voltage on Cl. A third capacitor is periodically connected to the nodes for sampling the input voltage, and connected between the output terminals of the first voltage follower and the integrator for subsequently also sampling and storing the integrated voltage on C2. The sum of the input voltage and the integrated voltage that is stored by C3 is discharged to the new input voltage when C3 is again connected across the nodes. The parallel combination of a grounded conductor and capacitor is simulated by replacing one of the voltage followers with a short circuit and connecting the associated node to ground. An inductor alone is simulated across the nodes by proper selection of values of the three capacitors.
