## What is the input offset voltage in an opamp?

Input offset voltage is the voltages aplied to the inputs of OP amp so as to take out zero voltage from the output of it. Normally, it is less than 1 mV, a noise level.

## What's the difference between non return to zero(nrz) and return to zero(rz) waveform

I think RZ is having more BER than NRZ. Manchester is having very less BER compared to other line coding schemes. Regards, tarak

## How to properly do AC open loop LDO simulation?

1/(C_OL*L_OL)^0.5 must be less than simulation min. frequency.

## Looking for a very low leakage mosfet

can anyone help me to find very low leakage mosfet ? zero gate voltage drain current should be less than 100 na. thanks

## auto Detection of the devices on the microcontroller

For the analog signals, it is easy: the 4-20mA range actually was designed especially to allow you to distinguish a loss of signal from a zero signal. Therefore, if you measure something that is much less than 4mA, you know there is no sensor present (or the wires are broken or shorted). For the digital signals you are describing, things (...)

## Can the noise figure of an amplifier be less than unity?

Can the noise figure of an amplifier be less than unity? as i made ADS simulation of noise, and obtain NF in values sometimes less than unity.. what's its units ? dB or ratio? Also, how can it be less than one?!?!?! thanks in advance, Ahmad,

## Supply independent current?

Mosfet are a active load BJT are the current, but the right one has a less current than the other one.

## Difference between zero-forcing algo and MSE algo

The structure of the two algorithms are similar, but multiplications in ZF are simpler (one of the terms comes from a small set of values). Their convergence properties are different: A necessary condition for the convergence of the ZF algorithm is that the eye must be initially open (peak ISI less than 1). MSE algorithm does not have this type of

## Power Modelling of embedded SRAM

Dear all, I am doing a project titled "Power Modelling of embedded SRAM". There are 2 types of SRAM cells that I need to take care of one is the standard SRAM and the other is the assymetric SRAM cell (where writing a zero is significantly less energy consuming than writing a one). The model should provide an estimate of the power (...)

## Please recommend an IC

hi, I need an IC which can perform the following function. (1) Just ONE voltage input, Vin. (2) Just ONE voltage output, Vout. (3) If Vin is less than a threshold (say, 1.8V), Vout is zero. (4) If Vin is larger than this threshold, Vout = Vin. I have considered to use a voltage (...)

## What is the SNR in this ADC ?

A signal with guassian distribution will have -9dB less than the maximun of SNR = 6.02n + 1.76 dB. Bastos

## Req: Using op amp for gain<1?

Ignore the replies about stability issues with NI amplifiers having a gain less than one. In this case the stability will be determined by the noise gain (from non-inverting input to output) which will approach 1 (from above) as the inverting gain is decreased towards zero.

## How to calculate the resistance and inductance of vias

DC-50MHz,the vias resistence and inductance can be ignored, They are very small ,less than 1OHm or 1nH.
