Design a full-wave rectifier power supply using a 9.52:1 transformer. Assume that the outlet is120 V rms @ 60 Hz. Further assume that the diode turn-on voltage V D(on) is 0.7 V. Pick the valueof CL such that vo has a maximum ripple of 1 V p-p . Solve for the average value of vo = Vo (notethat this may be greater than 12 V) and iD(ave) = ID.
Light-emitting diodes (LEDs) are diodes made with III-V compound semiconductor materials such as aluminum gallium arsenide (AlGaAs), aluminum indium gallium phosphide (AlInGaP) or indium gallium nitride (InGaN), instead of silicon. The LEDs emit light when the device is operated under forward bias. LEDs of different colors have different turn-on voltages VD(on). For example:
VD(on) :
Red: ~ 1.6 V
Yellow: ~ 1.7 V
Green: ~ 1.8 V
Blue: ~ 2.8 V
White: ~ 3.8 V
(a) Model these five LEDs with a simplified piecewise linear model
(b) A rule of thumb is that it takes about 1 mA of current to “light” an LED while ~ 10 mA is needed for it to appear bright. Use the piecewise linear model for the LEDs, for the over-voltage indicator circuit to the right, find the values of Vin which will cause D1 or D2 to light (i.e. when ID1 or ID2 exceeds 1 mA).
Consider a fixed and updated instrumentation amplifier (where two resistors are lumped into one
resistor), analyze the circuit if a common voltage source (VICM) is connected to two inputs.
