A New Trans-admittance Mode Biquad Filter using MO-VDTA

In this paper, a new trans-admittance-mode biquad filter configuration based on two multi output voltage differencing transconductance amplifiers (MO-VDTAs) as newly active elements is proposed which also consists of two grounded MOS resistors and two capacitors with one of the capacitor is being permanently grounded. The proposed configuration is competent of realizing trans-admittance-mode low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) filtering responses. Moreover, the proposed circuit offers several excellent features such as electronic tunability of pole frequency and quality factor, low active and passive sensitivity and low power consumption. To justify the theoretical analysis, the proposed circuit is simulated using PSPICE in 0.35μm CMOS technology from TSMC. Key-Words: VDTA, TAM, Biquad, Filter, Analog signal processing, Tunable.
