Abstract
A programmable device includes an operational amplifier and circuitry. The operational amplifier is configured to generate an output voltage based on input voltages at input terminals thereof. The circuitry is configured to provide the input voltages to the operational amplifier. The configuration of the circuitry allows the programmable device to implement discrete-time or continuous-time functions. The circuitry includes a resistor network and a capacitor network configured to be selectively coupled to the operational amplifier.
