A new low-voltage low-power CMOS current feedback amplifier (CFA) is presented in this paper. This is used to realize a novel digitally programmable CFA (DPCFA) using transistor arrays and MOS switches. The proposed realizations nearly allow rail-to-rail swing capability at all the ports. Class-AB output stage ensures low power dissipation and high current drive capability. The proposed CFA/ DPCFA operates at supply voltage of ±0.75 V and exhibits bandwidth better than 95 MHz. An application of the DPCFA to realize a novel voltage mode high-Q digitally programmable universal filter (UF) is given. Performances of all the proposed circuits are verified by PSPICE simulation using TSMC 0.25μm technology parameters.
