Current trends in consumer electronics demand progressively lower-voltage supplies. In this work, the aim is to utilize high efficiency low voltage DC-DC conversion which will efficiently generate each low supply voltage from a single battery source for portable devices. The converter is designed in a commercially available AMS® 0.35 μm CMOS technology and simulations performed in the Cadence A...

Lowering supply voltage of FinFET circuits is an effective way to achieve low power dissipations. In this paper, the super-threshold adiabatic FinFET circuits based on PAL-2N operating on medium strong inversion regions are addressed in terms of energy consumption and operating frequency. The supply voltage of the super-threshold circuits is much larger than the threshold voltage of the transis...

A CMOS implementation of a high-gain current mode operational amplifier (opamp) with a single-ended input and a differential output is described. This configuration is the current mode counterpart of the traditional voltage mode opamp. In order to exploit the inherent potential for high speed, low voltage operation normally associated with current mode analog signal processing, the opamp has be...

A 2.4 GHz CMOS up-conversion mixer using novel current mirrors based on chartered 0.18 μm RF CMOS technology for 2.4 GHz wireless sensor network (WSN) application is presented in this paper. The current-reuse current-mirror and current-bleeding technique are used in the driver and switching stages of the mixer, respectively. The post-layout simulation results demonstrate that the novel up-conve...

A new CMOS active mixer topology can operate at 1 V supply voltage by use of SCM (switched currentmirror). Such current-mode mixer requires less voltage headroom with good linearization. Mixing is achieved with four improved current mirrors, which are alternatively activated. For ideal switching, the operation is equivalent to a conventional active mixer. This paper analyzes the performance of ...

Abstract A new high-speed and low-power threshold detector is proposed to realize high-performance arithmetic VLSI systems. In a conventional threshold detector with a single supply voltage, the input signal swing of a differential-pair circuit (DPC) is too large, which causes large power dissipation together with a long switching delay. The use of two kinds of supply voltages makes the input s...

In this paper, a three-phase advanced static compensator (STATCOM) is proposed to compensate reactive power either for regulating ac supply voltage at a constant value or for unity power-factor and balancing of unbalanced reactive loads. An insulated gate bipolar transistor (IGBT) based current controlled pulse width modulated (CC-PWM) and voltage source inverter (VSI) is employed as the STATCO...

Digital circuits operating in the sub-threshold regime are able to perform minimum energy operation at a given delay. In the sub-threshold regime the circuit delay, and hence, the leakage energy consumption depend on the supply voltage exponentially. By reducing the idle time of the circuit, the energy-minimum supply voltage can be reduced, resulting in lower energy consumption. This paper firs...

A new current-source control technique is proposed to design a low-power high-speed multiplevalued current-mode (MVCM) integrated circuit in a low supply voltage. The use of a di erential logic circuit (DLC) with a pair of dual-rail inputs makes the input voltage swing small, which results in a high driving capability at a lower supply voltage, while having large static power dissipation. In th...
