The circuit shown in the figure is used to make a magnetic balance to weigh objects. The mass m to be measured is hung from the center of the bar, that is in a uniform magnetic field of 1.50 T, directed into the plane of the figure. The battery voltage can be adjusted to vary the current in the circuit. The horizontal bar is 60.0 cm long and is made of extremely light-weight material. It is connected to the battery by thin vertical wires that can support no appreciable tension; all the weight of the suspended mass m is supported by the magnetic force on the bar. A resistor with R = 5.00 Ω is in series with the bar; the resistance of the rest of the circuit is much less than this. (Figure 1) Figure 1 of 1 Part A Which point, a or b, should be the positive terminal of the battery? a b Submit Request Answer Part B If the maximum terminal voltage of the battery is 175 V, what is the greatest mass m that this instrument can measure?

(a) Figure Q2(a) shows a differential amplifier with a current source at the bottom. It is given that VDD = VSS = 15 V, ISS = 300 μA, Early effect can be ignored (λ = 0), Kn = 400 μA/V2 and VTN = 1 V. You may assume MOSFET in saturation region. (i) For single ended outputs, draw the half-circuits and derive the algebraic equations for the differential mode and common-mode gains as well as CMRR. [6 Marks] (ii) For the above case of single ended output, what should be the value of Rss to get CMRR = 100? [4 Marks] Figure Q2(a) (b) Figure Q2(b) shows a MOSFET based current mirror. Draw the AC small signal model and derive an equation for output resistance Rout as shown in the figure. You can keep your answer in terms of gm, ro etc but denote the subscript 1,2,3 etc to indicate which transistor. In other words, denote transconductance of M2 by writing gm2 and so on. [6 marks] (c) Draw the diagram of a BJT based Class B push-pull power amplifier and derive the maximum possible power efficiency of this circuit. You may ignore crossover distortion and assume |VCE(sat)| = 0 V. [9 marks]
