Zusammenfassung:A low-voltage digitally controlled current differencing buffered amplifier (DC-CDBA) is proposed. The realization scheme is through the cascade connection of a current differencing circuit, a current division network (CDN) and a buffered voltage amplifier. To achieve the digital control of the current gain of the circuit, a novel CDN is also proposed. The proposed DC-CDBA can operate with the low supply voltage of plusmn1.25 V. PSPICE simulations using standard 0.5-mum CMOS process parameters are in agreement with the theory.
