Combating Zener Jitter

May 21, 2017 26 Replies

The only app I would have at the moment is doing Bell inequality experiments with ~800 nm correlated photons. (I don't really know all the details of the experiment.) So I don't think I'd care about linearity. All the small pixels means smaller gain, as each photon triggers a smaller capacitance discharge.

One cool idea is to use a microchannel plate in front of a 2D delay-line detector. That can log the X-Y-T hits of single electrons or photons at a pretty high rate.

My only patent is for a delay-line detector, US7019307.

Is the low-voltage noise less than half, so it won't add up to more?

Yes, it's a tiny fraction. Try it.

Thanks, - Win

I am guessing you mean low frequency noise caused by flicker noise or else load regulation error caused by dynamic loads and the ratio of Zener ESR to dynamic load ESR, resulting in voltage error.

Can you be any less specific?

not have any of the normal zener avalanche noise

Can U be more explicit on this question?

Part number: Bias current. Noise level Vpp

- spectrum of noise, dominant, spread, slope

- impedance of circuit connected to zener; Resistance, inductance, capacita nce, length of wire/type balanced? unbalanced?

This is what I sarcastically meant by Can U be less explicit?

Thanks to R. Baer reference to Codatron shed some insight. 60 microamps i s the specified Ireg. and "standard models" are rated for +/-2% Voltage noi
