Question
What is Quiescent? What does it mean a transistor in saturation?
1. B= 0.01 A/V², V, = 0.6 V, Cgs = 0 (so far as we care) and VA = 20 V. %3D Calculate the DC Ipso for the circuit. a. IpsQ is the QUIESCENT Ips. i.e. the DC current in the circuit when there is no applied signal (the circuit is resting, if you like). It is also known as the bias point or the operating point. There is no IG, therefore V = VDp R2 -=3*(5/(5+4)) = 1.67 V %3D R, + R, We also have Vs = IDSRS and assuming the MOSFET is in saturation Ips (Ves -V,) %3D GS 2 where VGS = VG- Vs. This can be rearranged to give Ips =(Ve - InsR, – V,)°
