Abstract

A novel CMOS realization circuit of current controlled current differencing buffered amplifier (CCCDBA) based on compound MOS translinear loop and MOS current mirrors is presented. It presented such advantages as easy realization in the fabrication

simple circuit configuration

wide bandwidth

high voltage and current transfer accuracy and so on. The principle of circuit is analyzed in detail. To show the performance of the CCCDBA

a second-order current mode band-pass is evaluated from the literature

PSPICE simulation results for the proposed circuit in 0.5μm CMOS process is included

the simulation results satisfy theoretic analyzed.
