1.	Which transistor bias circuit arrangement has poor stability because its Q-point varies widely with β DC?(a) base bias(b) voltage-divider bias(c) emitter bias(d) collector biasThe question was asked in class test.The above asked question is from Input Bias and Offset Currents of the Bipolar Differential Amplifier topic in portion Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» Right choice is (a) base bias For explanation: In base bias IB, RB and IC are FIXED therefore it is also called fixed bias transistor. When the TEMPERATURE is vary then the Q point is also varied. Therefore base bias has no stabilization.
