lock-in amplifier howto
I am designing a gilbert mixer for using in lock-in amplifier. The LO and RF freqency is same(10kHz) to generate a dc voltage to be measured, I think it is a simplest useage for a mixer, can any one tell me if I need to use PSS, PAC and Pnoise in cadence to simulate the...
I know the ESD protection is very important for chip safety, but the chip I will design is to sense very weak current(lest than pA), so the leakage of ESD protection circuit shoud be less than pA, do you know, normally, how much current is the leakage from ESD protection?
If it is larger than...
I just wonder if we must include ESD protection on every pad?
In the low noise and low leakage current application, the input pad should be away from ESD protection, is it right? But is it safe from ESD?
Does anyone know if the commercial opamp input has ESD protection?
I plan to design a low noise pmos buffer, which need large input and output swing rang, I have two topologies, can any one tell me which one is better? or any other topology is better than these two? Many thanks
1. I have a 5uA current already in my design, can I use 10X current mirror to bias...
