Step 1 of 3 18.034P Refer to Figure P17.26 in the text book for the op-amp circuit. The output of the circuit is the voltage across the diodes as the diodes are connected in parallel across the output. The forward voltage drop of the diodes is +0.7 V When the voltage across the diodes is greater than +0.7 V one diode conducts and is directly connected to ground. Therefore, the maximum positive output voltage is +0.7 V Similarly, when the voltage across the diodes less than -0.7 V the other diode conducts and is directly connected to ground. Therefore, the maximum negative output voltage is -0.7 V. Therefore, the output levels are V Step 2 of 3 Apply voltage division rule to find the threshold levels. = = Draw the transfer characteristics, versus +0.7 -0.1 +0.1 -0.7 Step 3 of 3 Determine the maximum diode current. Substitute 12 V for saturation voltage, and 0.7 V for the diode voltage, 12-0.7 0.7 11.3 = =1.12mA Thus, the maximum diode current, is T
