A temperature sensor in a production line under normal operating conditions produces a no-load (i.e., sensor current = 0) voltage:
vs = Vpk cos(?t) Rs = 400?
Vpk = 500mV ? = 6.28 krad/s
The temperature is monitored on a display (the load) with a vertical line of light-emitting diodes. Normal conditions are indicated when a string of the bottommost diodes 2 cm in length is on. This requires that a voltage be supplied to the display input terminals where
Ro = 12 k? vo = Vm cos(?t) Vm = 6V
The signal from the sensor must be amplified. Therefore, a voltage amplifier, shown in Figure P8.2, is connected between the sensor and CRT with
Ri = 2k? Ro = 3k?
Determine the required no-load gain of the amplifier.
