ABSTRACT
This chapter presents the characteristics of diodes and discusses the operation of diode circuits. The Analog Discovery board is used to obtain diode I-V characteristics, and to study the characteristics of half- and full-wave rectifier circuits. The characteristic is divided into three regions: forward-biased, reversed-biased, and the breakdown regions. The chapter shows the effects of the time constant on the characteristics of a peak detector circuit. A peak detector is a circuit that can be used to detect the peak value of an input signal. Connecting a capacitor across the load of a bridge rectifier can smooth the output voltage of a full-wave rectifier circuit by filtering out the high-frequency components of the output signal. Determine the voltage at the output of a half-wave rectifier circuit built using the diode 1N4001. In the forward-biased region, the voltage across the diode is positive. Ideally, the diode conducts current in one direction.
