GM tester jig circuit<\/p>\n<\/div>\n

After a bit of work, got the transconductance jig working fine. Made an obvious omission which was not bypassing the CCS. The CCS present a very high impedance in AC to the circuit, therefore not developing the current variation on the measuring resistor. Bypassed by an electrolytic presents a path to ground.<\/p>\n","protected":false},"excerpt":{"rendered":"
