Abstract
A CMOS circuit configuration implementing a current feedback or transi mpedance op amp (CFB op amp) is presented. The architecture of the cir cuit is derived from similar bipolar CFB op amps. The properties of th e CMOS implementation are similar to those of its bipolar counterparts , i.e., a high slew rate and a bandwidth which is independent of the c losed-loop gain when the op amp is used with current feedback. Further , it is shown how two CFB op amps can be connected to achieve a non-sl ew-rate-limited voltage-mode op amp.
