The following circuit shows a MOS Wilson mirror in which Q1 and Q3 are matched, and they have the same (W/L)1 ratio that is 2 times of the (W/L)2 of Q2. All MOSFETs have the same Vt. 1) Derive the relationship between lout and IREF 2) Using small-signal model of the MOSFETs, derive and appreciate the output resistance of the current source, Ro.

Figure 1(a) shows a BJT based current mirror where the BJT current equation is given by: IC = IS′AEe VBE VT(1 + VCE VA) where Is′ = 50 fA, AE is normalized emitter area, thermal voltage VT = 25 mV and early voltage VA → ∞. Further, it is given that IREF = 0.5 mA, Vdd = 5 V and β = 50 for both Q1 and Q2. (a) Derive the equation of mirror ratio MR = Io/IREF. Using this, find Io, VBEI and VCEI if AE1 = 2, AE2 = 2. (25 Marks) (b) Suppose I want to increase the output current by increasing AE2 by 10 times. Recalculate MR = Io/IREF, Io, VBE1 and VCE1 if AE1 = 2,AE2 = 20. Does the output current increase 10 times compared to (a)? Marks) (c) What is the maximum mirror ratio attainable by increasing AE2 ? (10 Marks) Figure 1 2.

Figure P9.19 shows a MOS differential amplifer with the drain resistors RD implemented using diode-connected PMOS transistors, Q3 and Q4. Let Q1 and Q2 be matched, and Q3 and Q4 be matched. (a) Find the differential half-circuit and use it to derive an expression for Ad in terms of gm1,2, gm3,4, ro1,2, and ro3,4. (b) Neglecting the effect of the output resistances ro, find Ad in terms of μn, μp, (W/L)1,2 and (W/L)3,4. (c) If μn = 4μp and all four transistors have the same channel length, find (W1,2/W3,4) that results in Ad = 10 V/V.

Consider the circuit shown, which is a model of an amplifier. The input voltage is vs and the output voltage is vo. The resistance ro, has value 100K, which means 100 kiloohm (note the strange spelling) or 100 x 10^3 ohm. The value of the resistor r_pi is 2.5K (2.5 X 10^3 ohm). The controlled current source has transconductance gm = 0.04 S. This means that if the voltage across r_pi is v_pi, the current source has magnitude gmr_pi. Something that often confuses newcomers to electronics is the ground symbol: In the diagram, this symbol appears 4 times. All the grounds are connected and are, in fact, the same node. Using the information provided, find an expression for the ratio Av = vo/vs, which is called the voltage gain of the amplifier.
