I understand montecarlo analysis very well. What I have been doing is theoretical understanding of how offset and noise is defined? Now I want to do the same analysis in cadence. I am referring to input referred noise and offset? I understood noise analysis in different thread. I have simulated...
The simulation result of the noise analysis gives us the noise spectral density. How to choose the bandwidth so that to get (NSD * BW) to obtain value in volts(mostly in nv) or should I consider BW of the opamp or what do you mean by full bandwidth...
I have designed opamp previously. But have no idea on how noise is measured as seen in data sheet of opamp in terms of gaussian distribution. I want to understand how it is simulated in cadence for linear differential pair circuit. Generically, I have simulated gain, Phase margin, slew rate...
Hello guys!
I want to understand how to run noise analysis in cadence for differential amplifier. How to do it and come up with a value of spectral density for the noise present in the circuit. Thanks in advance.
I believe you, the best circuit for trans impedance amplifier will be CMFB opamp and not the one which you have mentioned. The circuit which you have used will be good only for input and output voltage (if you have load connected at output, either CL or RL). Transimpedance uses resistor at its...
I have a theoretical understanding of the effect of noise from different transistor and variations in different transistor. I want to know how to simulate in cadence.
For for the differential amplifier -
1. Theoretically noise is done individually for each transistor and then added up. The...
The main idea of telescopic opamp is to increase the gain by power of 2 (approx) instead of normal differential opamp. Considering the reduction in swing limits than to that of normal diff amp, I am wondering what would be the application of telescopic opamp. Anyone please enlighten me
hey! I have googled, the problem is i can understand the concept but dont know how to simulate in cadence. Its not something normal and its entirely related to signal processing which im new to it. Is there any proper manual on how to do it.

I have designed 12 bit linear ramp adc. I dont know how to measure the dynamic characteristics of the ADC. I run transient simulation for various values and find the output. Able to manage DC characteristics but I dont know how to run dynamic characteristics. I need some help on how to set test...
