Facts: Facts about Clampers A clamper is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined value by shifting its DC value. The clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as to place the peaks at the reference level. A diode clamp (a simple, common type) consists of a diode, which conducts electric current in only one direction and prevents the signal from exceeding the reference value; and a capacitor, which provides a DC offset from the stored charge. The capacitor forms a time constant with the resistor load, which determines the range of frequencies over which the clamper will be effective. Question: A clamping circuit has to have an independent source, a diode, a resistor, and a capacitor. To keep a constant voltage on the capacitor over the period of the input, the RC time constant must be large. A design rule of thumb is to make the RC time constant at…
Light-emitting diodes (LEDs) are diodes made with III-V compound semiconductor materials such as aluminum gallium arsenide (AlGaAs), aluminum indium gallium phosphide (AllnGaP) 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: Color VD(on) Red ~ 1.6 V Yellow ~ 1.7 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).
