1. ### basics of LDO - request for resources

basics of LDO Hi, I want to start LDO design. Could you provide documents for that.
2. ### waveform window question

This is not possible in spectre
3. ### why capacitive loads are drived by OTA?

to drive a capacitor, if we have a constant current source. that is good. ota acts constant current source., i.e, it's o/p i s current instead of voltage.
4. ### why do we use poly as gate?

why do we use poly as gate?
5. ### why do we use poly as gate?

why do we use poly as gate?

7. ### why do we use poly to connect poly

why do we use poly to connect poly
8. ### Why the ppen loop gain of an opamp is expressed by this equation?

Open Loop Gain because the gain depends onfrequency
9. ### Why do we use replica bias ?

replica-biased circuit Replica bias is used as bias for delayelements for VCO. It provide good stability over PVT such that freq. will not vary over PVT.
10. ### why oscillator o/p is sinusoidal?

this is ok for lc type oscillators. But what about ring oscillators.
11. ### Simple RC circuit interview questions

simple hpf circuit I f it is LPF, o/p levels will change fromQ1 to Q3.
12. ### why oscillator o/p is sinusoidal?

why oscillator o/p is sinusoidal or squarewave? for a simple RC circuit the o/p is not a sinusoidal. Then for a VCo how we r getting sinusoidal o/p
13. ### how to model PLL using MATLAB?

pll matlab example hspice is similar to spectre. for noise simulation we need hspiceRF or spectreRF.
14. ### how to model PLL using MATLAB?

pll model matlab Is simulink also part of matlab?
15. ### RMS jitter specification

I have rms jitter specification for a pll. what actually this refers to? Is this random jitter? If we do the phase noise simulation and calculate jitter value, what jitter we get?
16. ### how to model PLL using MATLAB?

pll matlab can any one suggest any papers how to model PLL in MATLAB?
17. ### How to decide PLL LoopBandwidths&#65311;

Hi amarnath, I didn't get the thesis from google. I f u have the link please give it.
18. ### about noise analysis of vco

what is ADS? is it some tool name?
