1.	The linear (active) operating region of a transistor lies along the load line below ________ and above ___________(a) cut off, saturation(b) saturation, cut off(c) active, saturation(d) cut off, activeThis question was addressed to me during an interview.My doubt is from Input Bias and Offset Currents of the Bipolar Differential Amplifier in chapter Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» Right choice is (b) saturation, cut off For explanation: Q-point is generally TAKEN to be the intersection point of LOAD LINE with the output CHARACTERISTICS of the transistor. That’s why; the linear operating region of a transistor must LIE along the load line below saturation and above the cut off.
