Problem 1: Consider 0.6µm CMOS technology (also known as 0.5µm CMOS) n-well process (p-substrate is lowest potential) with VTN0 = -VTP0 = 0.7 V, µnCOX = 115µA/V2 , µpCox = 50µA/V2 , λ = 0.1 V-1 , γ = 0. Ignore the channel-length modulation effect at the DC analysis onlv, use VDD = 1.8 V, Ix = 100µA, Vout is taken from the drain of Q1 and assume all transistors are in saturation with Lall_transistors = 1µm, Wn = 2µm and Wp = 1µm.

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
