4. A biased clamper is connected to a rectangular AC input with 20V on the positive half cycle and -10V on the negative half cycle. The orientation of the Si diode is the same with Vo while the 5V biasing voltage is in opposite connection. The value of R is 100K ohms while the capacitor is 1 microFarad. Find the voltage across the capacitor. Estimate the amount of time needed to fully discharge the capacitor. Find the magnitude of the output swing. Find the output voltage (Vo) during the negative half cycle. Find the output voltage (Vo) during the positive half cycle. Find the value of the Time Constant (Tau).

Specify the LM-series linear regulator required to regulate a fixed voltage of -19 V. Please write the numbers only in the answer field: i.e. for LM1234, you would write 1234 in the answer field.

A silicon diode has a forward voltage drop of 1.2V for a forward DC current of 100mA. It has a reverse current of 1μA for a reverse voltage of 10V. Calculate the: a. Bulk resistance b. Reverse resistance c. AC resistance at forward DC current of 2.5mA

2. A certain zener diode has a maximum power rating of 300 mW at 40 deg Cand a derating factor of 1.4mW/deg C. Determine the maximum power the zener can dissipate at a temperature of 80 deg C. 3. From the datasheet, a 1N4728A zener diode has a ZZ of 10 0. The datasheet gives VZ = 3.3 V at a test current, IZ, of 76 mA. What is the voltage across the zener terminals when the current is 90 mA? When the current is 45 mA?

double clipper circuit  Zener diodes 1N4733A has a voltage of 5.1 V and 1N4735A has a voltage of 6.2 V with a resistor R=300ohms has been used. you may like to increase the input to a 12 VRMS AC source in order to see the clipping at 7volt. Please, Do the theoretical calculations and plot the expected waveforms by hand. ( I have its multisim design and only needs theoretical calculation and hand drawn graph of it to compare to its data that I have collected  from multism.) Thanks
