(Hint: The average value of half-sine waves is VJr.) Ans. 3.133 AA 4.2 Terminal Characteristics of Junction Diodes The most common implementation of the diode utilizes a pn junction. We have studied the physics of the pn junction and derived its i-vcharacteristic in Chapter 3. That the pn junction is used to implement the diode function should come as no surprise: the pn junction can conduct substantial current in the forward direction and almost no current in the reverse direction. In this section we study the i-v characteristic of the pe junction diode in detail in order to prepare ourselves for diode circuit applications. Figure 4.7 shows the i-v characteristic of a silicon junction diode. The same characteristic is shown in Fig. 4.8 with some scales expanded and others compressed to reveal details. Note that the scale changes have resulted in the apparent discontinuity at the origin. As indicated, the characteristic curve consists of three distinct regions: 1. The forward-bias region, determined by v>0 2. The reverse-bias region, determined by v<0 3. The breakdown region, determined by < -V These three regions of operation are described in the following sections. 4.2.1 The Forward-Bias Region The forwand-hias-or simply forwand-reeion of oneration is cnterod when the terminal
