The below BJT common-emitter amplifier with β = 100 is fed with a signal source that has a resistance of 5 kΩ. A load resistor of 5 kΩ is connected to the output of the circuit as shown in the figure. The input resistance of the amplifier is Ri = 2 kΩ and its output resistance is Ro = 5 kΩ. Find the bias current (1), and the small signal parameters. Use VT = 25 mV. If the peak value of Vπ (denoted by V^π ) is to be limited to 5 mV, what are the corresponding peak value of Vsig (denoted by V^sig ) and peak value of V0 (denoted by v^0 ) in presence of the load resistor? Instructions: Use the given input and output resistance values and the equations related to these quantities (from the lecture notes) to find the small signal parameters and the bias current. To find the peak value of vsig, you need to draw the small signal circuit. replace v/with vsig in series with a 5 k resistor. From the signal circuit, find out how Vπ is related to Vsig. Calculate the open loop voltage gain, and use it with the given load resistor value and the voltage amplifier model to find out how V0 is related to Vsig in the presence of the load. You can also solve the signal circuit to find the answer. v^sig = 17.5 mV V^0 = 1.5 V v^0 = 0.4 V

Figure P7.33 shows a discrete-circuit amplifier. The input signal vsig is coupled to the gate through a very large capacitor (shown as infinite). The transistor source is connected to ground at signal frequencies via a very large capacitor (shown as infinite). The output voltage signal that develops at the drain is coupled to a load resistance via a very large capacitor (shown as infinite). All capacitors behave as short circuits for signals and as open circuits for dc. (a) If the transistor has Vt = 1 V, and kn = 4 mA/V2 , verify that the bias circuit establishes VGS = 1.5 V, ID = 0.5 mA, and VD = +7.0 V. That is, assume these values, and verify that they are consistent with the values of the circuit components and the device parameters. (b) Find gm and ro if VA = 100 V. (c) Draw a complete small-signal equivalent circuit for the amplifier, assuming all capacitors behave as short circuits at signal frequencies. (d) Find Rin, vgs/vsig, vo/vgs, and vo/vsig.
