2. BCD-to-seven Segment converter:A light emitting Diode (LED) is a PN junction diode. When the diode isforward biased, a current flows through the junction and the light is emitted.See Fig.2.5V270myFigure.2A seven segment LED display contains 7 LEDS. Each LED is called a segmentand they are identified as (a, b, c, d, e, f, g) segments. Figure 3.023456aaaaaaabggdFigure 3. Digits represented by the 7 segments The display has 7 inputs each connected to an LED segment. All anodes ofLEDS are tied together and joined to 5 volts (this type is called common anodetype).

A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction: 1: A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below. "Ideal" view of a diode + The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below: Diode "Modeled" view of a diode +51 Diode V Ideal Diode "Off" i=0| + U≤0 + I Therefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode: • Current i cannot be negative.

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).
