I want to close a NO relay whenever the photodiode sees IR light. This circuit doesn’t seem to do that. I rigged up 2 transistors (darlington) but that doesn’t seem to work either.Bipolar transistor biasing
Bias circuit requirements Signal requirements for class A amplifiers. For analog operation of a class A amplifier, the Q point is placed so the transistor stays in active mode (does not shift to operation in the saturation region or cut off region) when input is applied.LMx24, LMx24x, LMx24xx, LM2902, LM2902x, LM2902xx ...

A charge amplifier is an electronic current integrator that produces a voltage output proportional to the integrated value of the input current. This is effectively a measurement of the electrical input charge; hence the naming of the device.Powering microphones Video | Circuits | Electronics Design

The How and Why of VHF Parasitic Oscillation. In order to have a VHF parasitic oscillation in a HF amplifier three things are necessary: An amplifying device that has VHF gain, a feedback path from the output to the input, and a VHF parasitic resonaant circuit, in the output.How to make Battery Charger Circuit Using Silicon ...

5F6A Bassman Amplifier Modifications ... Adjustable Bias. To make the 5F6A's bias adjustable you simply replace the bias circuit's 56k resistor (connected to 15k resistor and ground) with a mini 50k linear pot (or trim pot) and 27k resistor. mon Emitter Amplifier (CE) Circuit Working ... ElProCus
The Amplifier is an electronic circuit that is used to increase the strength of a weak input signal in terms of voltage, current, or power. The process of increasing the strength of a weak signal is known as Amplification.
