Q. Discuss in brief on combination clippers ?
Combination clippers are a combination of biased positive and negative clippers. With a combination clipper, a portion of both positive and negative half cycles of the input can be removed or clipped.
The circuit action is as follows.When the positive input voltage is greater than V1v diode D1 conducts and diode D2 remains reverse biased.Therefore a voltage V1 appears across the load. The output stays at +V1v so long as the input voltage exceeds V1.On the otherhand during the -ve halfcycle,The diode D2 will conduct heavily and the output of - V2v appear across the resistor.
Q. Given that a silicon n-channel JFET has V P = 5 V and I DSS = 12 mA, check whether the device is operating in the ohmic or active region when v GS =-3.2 V and i D = 0.5 mA.
