In this question, you are asked to find the effective transconductance (Gm) and the resistance into the drain (Rx) of a common-source amplifier with source degeneration. Based on the results, the voltage gain of a common-source amplifier with source degeneration will be evaluated a) The figures shown below are a circuit to find the effective transconductance (G) of the NMOSEFT with source degeneration (left) and its corresponding small-signal circuit (right). It is noted that the output is shorted to VDD (ac grounded) since the definition of effective transconductance is the ratio between the short-circuit output current and the input signal voltage. Prove that Gm is given by Gm = id/vin = gm/1+gmRs In this calculation, the current passing through ro can be neglected since, in general, ro is very large when the NMOSFET operates in saturation region and so this current is very small. Thus, the indication of id is the current of the voltage-controlled current source (gmvgs) only. b) The figure shown below is the method to evaluate the resistance looking into the drain (i.e. Rx) of a source-degenerated NMOSFET. The circuit is shown on the left while the equivalent small-signal modeling is shown on the right. It is noted that the bias condition (VBiAS) is set so that the values of gm and ro, can be defined. Moreover, there is no input signal (i.e. Vin = 0) since we would like to see the value of Rx which is due to the circuit only but not due to the external effect. Based on the above small-signal model, prove that RX = ro(1 + gmRS) The complete common-source amplifier with source degeneration is shown below. c) The complete common-source amplifier with source degeneration is shown below. Prove that the voltage gain of this amplifier is given by v. Vin Explain the reason(s) why the voltage gain is negative. What is the physical meaning of negative voltage gain?

Problem 3: (Short Circuit Power Consumption) For the circuit in Figure 2, assume that the input Vin is a periodic square wave signal (called "clock") of frequency 200 MHz, and has a rising transition time (from 0−100% of VDD ) of 0.2 ns and a falling transition time (from 100−0% of VDD ) of 0.2 ns. For the inverter in the figure, find the short circuit power consumption. Use the procedural hints listed below. Procedural Hints:Calculate the short circuit duration, tsc. Short circuit currents occur when both nMOS and pMOS transistors are simultaneously ON. Use the rise/fall times given. Calculate the peak short circuit currents. For simplicity assume that Ipeak_sc_LH and Ipeak_sc_HL are equal, and calculate the latter only. To calculate Ipeak_sc_HL, , assume that the short circuit current for the H-to-L transition peaks when Vin = VDD/2 and Vout = 9 VDD /10 (this is an arbitrary choice assumed for this problem alone). Now calculate the pMOS transistor current - this will be Ipeak_sc_HL. . Question: Does the nMOS current equal the pMOS current? If not, how do you account for InMOS−IpMO ? Using your results from (1) and (2), calculate the short circuit power dissipation. Note: Assume that VDD = 1.0 Volts, (W/L)p = 3.5 /0.1, and (W/L)n = 2 /0.1. Transistor properties are given by the 90 nm model parameters handout posted on the class web-site. For the current calculation, use the transistor parameters (not the equivalent resistance parameters) and ignore channel length modulation. Assume that there is an 89 fF load on Out.

Consider two blocks M1 on top of M2 on a level table. There is no friction between block M2 and the table, but there is friction between block M1 and block M2. Denote the coefficients of static and kinetic friction between the blocks as μs and μk, respectively. The applied force F is applied to block M1 at an angle θ below the horizontal. The blocks start from rest. First, we will consider the situation where F is small enough that the two blocks stick together. (a) Draw free-body diagrams for the two masses. Be sure to label all forces and the direction of the accelerations. Also be sure to define an appropriate coordinate system for each free-body diagram. (b) Write down the Newton's second law equations for each block and each dimension (x and y). (c) Write down an inequality relating the force of friction and the normal force. (d) Identify the two Newton's third law pairs - i. e. the pairs of forces between the two blocks that are equal and opposite. (e) Find the acceleration of the blocks as a function of F, θ, M1, M2, g, μs, and μk. (You don't have to use all of these, but you will use at most these. ) (f) Find a condition on F such that the blocks stick together. i. e. Write an inequality in the form F ≤ Fmax for the blocks to stick together where Fmax is in terms of θ, M1, M2, g, μs, and μk.
