Abstract

This article presents the design for a basic current mode building block for analog signal processing, called Current Controlled Current Differencing Buffered Amplifier (CC-CDBA). Its parasitic resistances at two current input ports can be controlled by an input bias current. The output current and voltage offset are quite low. The proposed element was realized in a BiCMOS technology and the voltage follower in the element is modified to achieve high performance properties. Its performances are examined through PSPICE simulations. In addition,
examples as a current-mode multiplier/divider and current amplifier are included, compared to the conventional CC-CDBA implementation. They disclose performances of the proposed CC-CDBA superior to previous CC-CDBA.
