Chapter 4, Problem 1P

An amplifier has a gain of 15 and the input waveform shown in Fig. P4.1. Draw the output waveform.

To determine

To draw:

The output waveform using input waveform and gain of the amplifier.

### Explanation of Solution

Given:

Amplifier has a gain of 15 and input waveform shown below.

Calculation:

For an amplifier, output voltage is product of gain and its input voltage.

vo=Avin

Wherevo=Outputvoltagevin=InputvoltageA=Voltageamplifiergain

In the given figure, calculate the output voltage by the above formulae at different time to form a graph.

At t=0 ,output voltage will be

vo=15×(0mV)=0mv

At t=0.5s ,output voltage will be

vo=15×(50mV)=750mV

At t=1s, output voltage will be

vo=15×(150mV)=2250mV

At t=1.5s, output voltage

vo=15×(50mV)=750mV

At t=2s, output voltage

vo=15×(0mV)=0mV

The output waveform for the given input is shown below.

4.90 A reverse-biased photodiode is specified to have a dark current of 100 pA and a responsivity of 0.5 A/W. It is connected to the transresistance amplifier shown in Fig. P4.90. Assume an ideal op amp. (a) What is the reverse-bias voltage across the photodiode? (b) What is the output voltage vo with no illumination? (c) What is the output voltage vo with 10 µW of light incident on the photodiode? 250 kN On o +3 V. Figure P4.90 Hint: since we are assuming an ideal op amp, there is a virtual short-circuit between input terminals.
