Abstract

This paper proposes a new purely active floating resistance simulation circuit employing two voltage differencing trans-conductance amplifiers (VDTAs). The proposed configuration enjoys following advantageous features; (i) purely active realization (ii) electronically tunable resistance (iii) no requirement of any active/passive component matching constraint (iv) good non-ideal behavior and (v) low sensitivity values. The Influence of VDTA terminal parasitics on high frequency behavior of proposed circuit is also investigated. 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.
