Original Abstract

A controllable modification of current feedback amplifier is presented in this contribution. In spite of classical conception, there are two current outputs of both polarities available and two buffered voltage outputs. The control of parameters consists of adjustable current gain between X and Z ports and intrinsic input resistance of current input (X). We proposed complex model of active element, which is based on CMOS and bipolar available transistor models of process technology. Spice simulations confirmed our presumptions and provided features of designed active element.

Keywords

Spice simulation and modeling, electronic control, current feedback amplifier, double current controlled CFA.
