Abstract
Several modeled conceptions of current follower (or amplifier) with electronically adjustable input (intrinsic) resistance and current gain (in case of amplifier) are presented in the contribution. Features of proposed models are documented by symbolical analyses when considering important parasitic small signal properties. An example of behavior of such model is verified by simulations in PSpice. Described approaches allow design of applications without external (in IC case) floating resistors. Simple examples of two functional adjustable voltage mode biquad and oscillator are included.
