redoing last experiment

A project log for enhancement to depletion

DIY method to lower gate threshold voltage of regular MOSFETs, ultimately reversing it.

In progress now. So far, it is going rather similarly to a previous one, even though that previous one was done on defunct circuit.

The threshold voltage is now rising again.


UPDATE: finished.

Unprocessed data available in files: TORTURE2.TXT. Note: torture currents are chopped with 50% duty cycle, so the average currents into gate are half the indicated values.

Kinda similar to what I got with broken circuit. Except, this time:

* fresh transistor

* final current was 1 uA, not 0.3 uA

* I almost reached the end of the process =)

Wow... A single MOSFET could create a very very slow time constant... of course, temperature dependent :-D

  Are you sure? yes | no
