The research on the design of receiver front-ends for very high data-rate communication in the 60 GHz band in nanoscale CMOS technologies is going on for some time now. While a multitude of 60 GHz front-ends have been published in recent years, they are not consequently optimized for low power consumption. Thus, these front-ends dissipate too much power for battery-powered applications like han...

In this paper, CMOS Sample-and-Hold (S/H) is presented. The S/H circuit is an important component in Analog-to-digital Converter (ADC). In low frequency application, the boost clock technique is used to constitute a rail-to-rail signal voltage with low distortion. The operational amplifier works as a unity gain buffer in the S/H circuit. However, a two-stage op-amp is proposed with enhanced low...

In this article, a novel circuit, which can function both as quadrature oscillator and universal biquad filter (lowpass, highpass and bandpass functions) is introduced. The features of the circuit are that, working as quadrature oscillator, the oscillation condition and oscillation frequency can be adjusted independently with the input bias currents: functioning as universal biquad filter, the ...

In high-speed high-resolution analog to digital converters, comparators have a key role in quality of performance. High power consumption and delay is one of the drawbacks of these circuits which can be reduced by using suitable architectures. Many versions of comparator are proposed to achieve desirable output in sub-micron and deep sub-micron design technologies. Back to back inverter in the ...

In this paper, a Least Mean Square (LMS) programming scheme is used to set the offset voltage of two operational amplifiers that were built using floating-gate transistors, enabling a 0.95 VRMS trimmer-less flame detection sensor. The programming scheme is capable of setting the offset voltage over a wide range of values by means of electron injection. The flame detection sensor consists of two...

HE OUTPUT NOISE of signal amplifiers usually inT creases when the signal bandwidth increases. In addition, the use 'of low-value resistors is recommended in low-noise voltage amplifier design in order to reduce the contribution of their thermal noise to the output noise [ l ] , [ 2 ] .
