Sense amplifiers are one of the most vital circuits in the margin of CMOS memories. Their performance influences both memory access time and overall memory power dissipation. The existing Current-Mode Sense Amplifier coupled with a simplified read-cycle-only memory system has the ability to quickly amplify a small differential signal on the Bit-Lines (BLs) and Data-Lines (DLs) to the full CMOS ...

A fully differential biquadratic filter section for data acquisition in smart sensor microsystems is proposed. The architecture of this biquadratic filter section is built upon a resonant fully differential topology based on a new Fully Differential Multiple Differences Amplifier cell (FDMDA). This biquadratic low-pass Butterworth filter has two differential inputs that can be algebraically sum...

Growing interest in the electrical properties of living organisms has required the development of amplifiers sufficiently sensitive and stable to record the minute changes in potential encountered. Such amplifiers must be of high gain, with differential input (so that several amplifiers may be used simultaneously on one specimen), freedom from voltage drift, and should be direct coupled through...

The conventional integrated-circuit operational amplifier (IC op amp) is typically designed for split power supplies (±15 ...

A new linearization technique for a CMOS high frequency mixer will be presented. The reduction of the total harmonic distortion coefficient is achieved by replacing the simple differential amplifier from the basic multiplier circuit with a cross-connection differential amplifier, with the advantage of canceling the third-order harmonic from the output signal expression. The circuit was implemen...

This paper presents a second order voltage mode quadrature sinusoidal oscillator using a recently reported active building block, namely the differential voltage current controlled conveyor transconductance amplifier.

1. Abstract The localized heating of semiconductor devices on an integrated circuit can cause pronounced change in the operating characteristics of the circuit. This work proposes a mathematical model to calculate the changes in the output parameters of a FD SOI MOS used in the integrated circuits. The device characteristics change due to non-linearity in operation of the high heat dissipating ...

Stochastic anti-resonance, that is resonant enhancement of randomness caused by polarization mode beatings, is analyzed both numerically and analytically on an example of fibre Raman amplifier with randomly varying birefringence. As a result of such anti-resonance, the polarization mode dispersion growth causes an escape of the signal state of polarization from a metastable state corresponding ...

Single-ended and differential operational transconductance amplifier (OTA) configurations are biased with MOSFET interface-trap charge-pumping (ITCP) current generators to achieve very low transconductances for tunable sub-hertz operational transconductance amplifier-capacitor (OTA-C) filter implementation. This paper reviews the basics of ITCP current generation and presents the transconductor...
