New CMOS based current follower and its applications to inductor simulator and band-pass filter

Yuce, Erkan ; Alpaslan, Halil


A new CMOS based current follower (CF) with externally controllable X terminal intrinsic resistor has been proposed in this manuscript. Also, a new electronically tunable grounded inductor simulator using only a grounded capacitor has been proposed. The inductor simulator does not need any external resistors. It can be tuned electronically by changing a control voltage. However, it has a single active component matching condition. The simulations results are given in order to demonstrate the performance of the circuits.
