For the fixed-bias configuration, determine the following: a. IBQ. b. Ico. c. VCEQ. d. Va.. e. Ve f. VE.. 16 V Ice 1.8 k2 510 k2 Vc VB |VCEQ B=120 IBQ VE

The average value of the output voltage with PWM is Vo = 5 V. If the on state duration Ton is 5 µs and supply voltage Vin = 20 V, find the duty ratio d, switching period Ts and switching frequency fs of the system. Draw the waveforms for Vin and Vo voltages stating on and off durations.

The resistors you can use in the shown below circuit have a maximum power dissipation level of 1W. If the diode has an absolute maximum rating of 1A, and can be modelled with a diode drop of 0.7 V. The maximum output voltage of the variable supply (VIN) is 14 V. What is the minimum value of resistance (R1) that can be used in this circuit? FT Vin R1 Vout
