A multioutput current-controlled current conveyor (MOCCCII)-based function generator is proposed, which provides a mixed-mode sinusoidal four-phase quadrature outputs, square and triangular voltage outputs simultaneously. The starting building block of the proposed function generator is a single output current-controlled current conveyor (CCCII)-based voltage-mode sinusoidal quadrature oscillator...
A three-output transconductance element (TE) with two complementary MOS transistors and a grounded resistor are used to realize a non-inverting and an inverting precision full-wave rectifiers. The attractive features of the proposed full-wave rectifier circuits are high input impedance, large input operating range from -500 mV to 500 mV, high frequency operation up to 200 MHz, low zero crossing distortion,...
Electronically controlled non-inverting and inverting precision rectifier circuits employing a CMOS three outputs operational transconductance amplifier, two MOS transistors and two grounded resistors are proposed. The circuits have the attractive features such as, high input impedance, large input operating range from -600 mV to 600 mV, electronically controlled output, high frequency operation up...
A simple scheme is given for the realization of a voltage mode four-phase sinusoidal oscillator (VMFPSO). Using this scheme a VMFPSO employing second-generation current conveyors (CCIIs) as the active devices with grounded passive components is realized. The VMFPSO is then transformed into a dual output current conveyor [DO-CCII]-based voltage mode eight-phase sinusoidal oscillator (VMEPSO) by replacing...
Some multiphase sinusoidal oscillator circuits either employing two output second generation current conveyors [DOCCIIs] or multioutput current conveyors [MO-CCIIs] as the active devices with grounded passive components are proposed. Two [DO-CCII]-based oscillators can generate odd-phase and some even-phase output voltages while the other two can generate both odd-phase as well as even-phase output...
A function generator circuit using positive type second-generation current-controlled current conveyors [CCCII+]-based voltage mode non inverting band-pass filter (BPF) as a starting building block is proposed. A direct feedback path from the output to the input of the BPF is provided to obtain a sinusoidal oscillator. Then, [CCCII+(2)] of the sinusoidal oscillator is replaced by multioutput current-controlled...
