The low-noise amplifier shown uses a rare Raytheon operational amplifier today. The circuit can be implemented with more modern operators and the power source must be symmetrical.
This circuit can be used with 5 to 15 V sources and the zener diode must be chosen according to...
Here we show how a Constant Current Source can be created in the Multisim Blue using a common BJT...
This circuit was found in a 1964 Electronic Design. The circuit makes use of transistors of the...
