Novel Applications of VDVTA: As Current-Mode SIMO-Type Biquad and Electronically Controllable Sinusoidal Oscillator
نویسنده
چکیده
In this paper we present new applications of voltage differencing voltage transconductanse amplifier (VDVTA) as current-mode (CM) biquad filter and electronically controllable sinusoidal oscillator (ECSO) using single VDVTA and with four passive components, three passive components respectively. The biquad circuit realizes low pass, high pass, and band pass filter simultaneously without changing the circuit topology. The oscillator circuit also enjoys the explicit current output and also the frequency is electronically controllable. The active and passive sensitivities for both circuits are very low. Both the circuits are simulated using PSPICE with TSMC CMOS 0.18 μm process parameter
