Abstract

In this paper, a new circuit based on single voltage differencing trans-conductance amplifier (VDTA) is presented which realizes band pass (BP) and high pass (HP) filtering functions in trans-admittance-mode (TAM). In addition of single VDTA as active element, it also consists of two grounded capacitors and one resistor as three passive elements. Moreover, the proposed circuit can be operated at low voltage (±1V) power supply which results low power consumption. The circuit also exhibits low active and passive sensitivity. The validity of proposed filter is verified in CMOS technology through PSPICE simulation.
