1. Signal Generation a. In PSpice, pick LM324 or uA741 (for U1 - U3 op-amps), construct the circuit in Figure 1. Use dual power supply of V+=+9 V for the op-amps, Rref_1 and Rref_2. b. Start with the values in Table 1, simulate the transient response of the circuit. (You define the transient time duration for appropriate cycles of waveforms.) c. Compare the voltage at the output node of each stage (V1, V2 and Vin). d. Based on your observation of the waveforms at each stage, identify and discuss the function of each block in the circuit. e. Modify Ry or C, observe how the frequency of the response changes. f. Change Rref_1, check how Vin changes accordingly. g. Draw conclusions on the functions of the overall circuit and individual blocks. R2 R w V+ C C R Rota JU w RI V1 U2 V2 w R Ret 1 oy. Figure 1. A circuit to generate Vin. (Here Vin means the input to the next stage of power amplifier.) You may start with the following parameters for the circuit. EEER Parameters R R2 R3 R4 Values 10 k 10 k 100 k 100 k 200 k Parameters Reef 1 Rref 2 С C2 V+, V-for op-amps and voltage divider Values 10 k 20 k 1.0 uF 10 nF +9V
a. 2. Power Driving Circuit 1) Single transistor driver Connect the circuit in Figure 1 to the single MOSFET in Fig. 2. Choose IRF150 for the NMOSFET. Set R= 10 k12, RLoad = 10 12. You may include a LED as part of RLoad to visualize the effect. b. Repeat the transient simulation in last section. Observe the voltage across the load resistor RLoad (i.e. V+- Vload) and the current passing it. c. Derive the power consumption by RLoad. Find the relation of the power consumption and the duty cycle of Vin d. If Rload is a DC motor, what will be changed with a vin in Fig. 1 that has a changing duty cycle? Comment on the connection and the result. e. Rload o Vload . Vid RS Figure 2. Powering load using a single N-MOSFET.
