Description
Summary:This paper proposes a new active synthetic floating resistor circuit employing three voltage differencing transconductance amplifiers (VDTAs). The proposed configuration enjoys following advantageous features; (a) purely active realization (b) electronically tunable resistance (c) no external component matching constraint(s) (d) good nonideal behavior and (e) low sensitivity values. The workability of proposed resistor simulator has been verified by an application example of voltage mode low-pass filter. To validate the theoretical analysis SPICE simulations with TSMC 0.18µm CMOS process parameters have been performed.
