The reliable operation of SRAM in presence of process variation in sub-100nm devices is largely influenced by periphery circuits, like sense amplifiers, demanding more robust solutions. A new differential sense amplifier for use in standard 6-T SRAM based on gated-diode is proposed and designed. For comparison, three other latch-based sense amplifiers are also designed in 45nm technology. The b...

A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 mm CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential ...

A class E power amplifier including coupling coils is proposed for application in a wireless power transfer system using magnetic coupling. The proposed amplifier is directly connected to the coils with no discrete components for harmonic filtering and dc feeding, which could cause efficiency degradation of the amplifier. The system with the differential amplifier shows 6.95 W of transmitted po...

This paper describes the design and performance of an extremely low-noise differential transimpedance amplifier, which takes its two inputs from separate photodiodes. The amplifier was planned to serve as the front-end electronics for a highly sensitive shadow-displacement sensing system, aimed at detecting very low-level "Violin-Mode" (VM) oscillations in 0.4 mm diameter by 600 mm long fused-s...

The paper presents a new voltage-mode universal filter using a differential voltage current conveyor transconductance amplifier (DVCCTA). It has three inputs and single output. The proposed circuit can simultaneously realize low-pass, band-pass, and high pass, band reject and all pass filter functions without changing the circuit topology and passive elements. The circuit exhibits a good freque...

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

The design of a fully differential CMOS transconductance amplifier is presented in this paper. This amplifier is to be used in the first stage of a 13-bit pipelined A/D converter, and was designed to meet the necessary specifications at a minimum level of power consumption. The amplifier presented below was based on a two-stage design of a telescopic cascode input stage followed by a common-sou...
