- In this parallel negative clipper and positive clipper difference between the diode orientation
- in this paralle negative clipper have a diode and one resistance and another one is load resistance
- During positive half cycle the diode becomes reverse biased and entire current will flow through the load resistance
- When the diode is reverse biased the diode act as oprn switch or loop no current flows through the diode
- During negative half cycle the diode will be forward biased and entire curent will flow through the diode
- When the diode is forward biased and the diode act as a close switch or loop the entire current will flow through the diode

Miller Crystal Oscillator Miller Crystal Oscillator Similar to modifications in Colpitt's oscillator, the Hartley oscillator circuit can be modified, to get Miller crystal Oscillator In Hartley oscillator circuit, two inductors and one capacitor is required in the tank circuit. One inductor is replaced by the crystal which acts as an inductor for the frequencies slightly greater then the series resonant frequency. The tuned circuit of L1 and C is offtuned to behave as an inductor i.e. L1. The crystal behaves as other inductance L2 between base and ground. the Internal capacitance of the transistor acts as a capacitor required to fullfill the elements of the tank circuit The crystal decides the operating frequency of the oscillator.
