A new circuit configuration uses a single operational transresistance amplifier (OTRA) and four passive elements to realize both first-and second-order allpass filters. Owing to internal grounding of the OTRA input terminals, effects of input parasitics are significantly reduced. Applications of the circuit include the realization of the phase equalizer, the quadrature oscillator, and the high-Q bandpass filter for analog signal processing. The performance of the allpass filter is illustrated by circuit-level simulation of a quadrature oscillator with CMOS realization of the OTRA.
In this paper, a voltage-mode full-wave rectifier employing plus-type second-generation current conveyors (CCII+s) and enhancement-mode n-channel metal-oxide semiconductor field-effect transistors (MOSFETs) is proposed. The presented circuit requires no passive components, and is suitable for high frequency applications. The proposed full-wave rectifier circuit is simulated using HSPICE to verify the theoretical analysis
In this work, a voltage-mode canonical first-order all-pass filter is presented. The filter contains only a single resistor, a single capacitor, and a single differential difference current conveyor (DDCC). No passive component-matching constraints are required. A complementary metal oxide semiconductor CMOS implementation of a DDCC is given to simulate the proposed circuit with a Spice simulation program whose results illustrate the high performance of the circuit.
