Patent ID: 7002498

Claim:
A method for demultiplexing an input signal (V IN ) using an input amplifier (A 1 ) and a plurality of output amplifiers (AMP 1 –AMP N ), the input amplifier (A 1 ) having first and second inputs and an output, the output amplifiers (AMP 1 –AMP N ) each having first and second inputs and an output, the method comprising the steps of: providing a first input capacitor (C S1 ) having a first terminal, and having a second terminal connected to the first input of the input amplifier (A 1 ); providing a second input capacitor (C S2 ) having a first terminal, and having a second terminal connected to the second input of the input amplifier (A 1 ); accepting the input signal (V IN ) at an input terminal ( 2 ); selectively connecting the input terminal ( 2 ) to the first terminal of the first input capacitor (C S1 ); selectively connecting the input terminal ( 2 ) to the first terminal of the second input capacitor (C S2 ); selectively connecting the output of the input amplifier (A 1 ) to the first input of one of the output amplifiers (AMP 1 –AMP N ); and selectively connecting the output of one of the output amplifiers (AMP 1 –AMP N ) to the first terminal of the first input capacitor (C S1 ).
