RC integrators and capacitors both store charge on the capacitor based on the input voltage.
1. What is the main difference in operation between the two?
2. Why and when would you use one over the other?
I'm still confused about settling 'linearly'. Intuitively, when the output is near the final value, it will behave exponentially, getting infinitesimally closer to the final value. How can this behavior 'linear'?
"The amplifiers don't linearly settle when there are large signals are present as input."
What does settling linearly mean? Signals settle exponentially because of charging/discharging caps? How is this different from slewing?
I have a transmission gate flip flop with NOR gates for set/reset . In simulation, this flipflop works fine at high frequencies ~10MHz but when I clock it at 100 kHz, it starts to fall apart. Does transmission gate FF not work for frequencies below 100 kHz?? I'm using 90 nm cmos.
I'm designing a mixer in ADS and I'm trying use its optimization function to help me.
I can set optimize for noise figure, ip3_out, but I'm not able to set a goal for conversion gain as ADS does not have a block that calculates this (AFAIK). So I tried making a equation for conversion gain but...
Say for example, if a colleague asked you how to verify PCIe? Can you describe briefly how you go about doing this from a verification perspective? What you would test and how etc? I just want to get a idea what kind of things I should look at.
The traditional RC integrator is implemented with an ideal opamp with RC. I've seen some integrators with OTA with the same RC configuration.
Why does this work? OTA has high output impedance right?
Opamp with diff pair with single ended output with Rl as the load would give you Aol = gm*(ro||Rl). no?? or is this OTA?
I know that opamp just has a buffer at the output so what would be the VOLTAGE of the opamp with the above opamp with buffer?
Thanks!
