1. create a circuit which will only accept the positive half cycle and consider the diode as a Silicon, but this time apply a capacitor to smooth out the pulsating dc (make it as smooth as possible).   2. create a circuit that will only accept the negative half cycle and consider the diode as a Silicon, but this time apply a capacitor to smooth out the pulsating dc (make it as smooth as possible).

SOLVE STEP BY STEP IN DIGITAL FORMAT For each of the circuits shown below, draw its voltage transfer curve, using the constant-drop model (all diodes are silicon identical, V_Don = 0.7V). Consider a variation of the input voltage from -10V to +10V. Vi V₁ D₁ D₁ Z D₂ 1k Circuit 1 1k Circuit 2 V₂ + V₂ Vi Vi 1k 1k D₁ Circuit 3 D₁ 1k ww 1k Circuit 4 + V₂ + V₂

I need an elaboration of this please... Thank youu.

as soon as possible please

quick reply needed.

Consider the following diode circuit. 1kQ Vs 10 Vs VD t(ns) 10 -5 i. Calculate the current at t=0* in the circuit. ii. Calculate lş and IR when the diode is switched off at t=10 ns. Assume Von=0.7 V. i. Write the type of capacitances in a diode.

-VBIAS + 0.7 VBIAS - 0.7 -VBIAS - 0.7 With the given circuit below, before the diode will become forward-biased and conduct, the voltage must equ v VBIAS + 0.7 Silicon diode) at the point before diode. R1 I D, VIN VOUT VBIAS =

just The third and fourth question

Q2) For the circuit shown in Figure 2, sketch the output voltage (across the load 2.2 KO resistor) and the load current (through the load 2.2 KN resistor). Sketch the diode voltage (across the diode D1) and the diode current (through the diode D1). The input Vi is sinusoidal with maximum amplitude (peak) of 14.1422 V and frequency of 60 Hz. The diode D1 is a Silicon diode. The sketches have to be at least for two cycles of the input. D1 2.2 K2 Vi

If the forward voltage drop on a diode is 780 mV, what is the current passing through it? Assume Is=4x10-16 A. O a. 6.412 mA O b. 5.343 mA O c. 4.275 mA O d. 7.481 mA O e. 3.206 mA
