A single input and three outputs voltage-mode multifunction biquadratic filter using a single plus-type differential voltage current conveyor, two capacitors and three resistors is presented. The proposed circuit offers the following features: realization of three filter functions, which are, lowpass, bandpass, and highpass filters, simultaneously, the use of only single plus-type differential voltage...
In this paper, a new active element called voltage differencing inverting buffered amplifier (VDIBA) is presented. Using single VDIBA and capacitor a new resistorless voltage-mode first-order all-pass filter is proposed, which provides both inverting and non-inverting outputs at the same configuration simultaneously. The pole frequency of the filter can be easily controlled by means of internal transconductance...
A CMOS inverter based amplifier operable down to 0.8 V of power supply has been proposed. The CMOS inverter amplifier has a level shifter circuit at its input to effectively reduce its threshold voltages. The level shift is realized by feeding an input signal via a resistive voltage divider which is connected between VDD and GND. The proposed amplifiers are used to construct a three-stage active RC...
