The very fast growing market of portable equipment is increasing interest in low power integrates circuit. So, designing low power integrated circuits requires reduction of supply voltages and interconnection parasitic to minimum but reduction in supply voltage implies series of problems in circuit design. To overcome these issues, an Ultra low power low voltage two stage class AB CMOS fully di...

This paper proposes a realization of power factor function generator having an arbitrary base and power factor which are determined by the ratios of the currents provided from outside of the circuit. The circuit characteristics do not depend on any transistor parameters, temperature, and other environmental conditions. The circuit operation is based on current mode that has a capability of low ...

A new first order voltage mode all-pass filter circuit using two differential difference current conveyors (DDCCs) (with suppressed output stages) as active elements and two passive components is proposed. The given circuit enjoys the features of high input impedance and low output impedance, which is desirable feature for voltage-mode circuits. In spite of employing two active elements the cir...

A new precision peak detector/full-wave rectifier of input sinusoidal signals, based on usage of dual-output current conveyors, is presented in this paper. The circuit gives a DC output voltage that is the peak input voltage over a wide frequency range, with a very low ripple voltage and low harmonic distortion. The proposed circuits use an all-pass filter as a 90 ̊ phase shifter of the processe...

A low-voltage low-power CMOS operational transconductance amplifier (OTA) with near rail-to-rail output swing is presented in this brief. The proposed circuit is based on the current-mirror OTA topology. In addition, several circuit techniques are adopted to enhance the voltage gain. Simulated from a 0.8-V supply voltage, the proposed OTA achieves a 62-dB dc gain and a gain–bandwidth product of...

In this paper, a new D-latch topology has been implemented in MOS Current Mode Logic (MCML) that works on lower supply voltage than the D-latch topology already implemented in MCML. The already implemented D-latch topology is called Traditional DLatch Topology and the new D-latch topology that works on lower voltage is called low-voltage D-Latch Topology. Power consumed by MCML circuit is direc...

In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy tra...
