What is the function of a bias circuit?(a) To simplify the circuit(b) To provide a non – linear output(c) To optimize the power(d) To provide steady current or voltageI had been asked this question by my college director while I was bunking the class.My question is from Stabilization against Variations in VBE and Beta for Self Bias Circuit topic in division Transistor Biasing and Thermal Stabilization of Electronic Devices & Circuits

Answer»

The correct answer is (d) To provide steady current or voltage

The best I can EXPLAIN: The Q – point of a device is the direct current or voltage of a device when no INPUT is applied. The BIAS circuit is a part of the device with provides the steady current or voltage. It is DESIGNED by determining the necessary voltage and current LEVELS across each resistor.
