Q1. In this question, you are asked to find the effective transconductance (Gm) and the resistance into the drain (R) 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 (Gm) of the NMOSFET with source degeneration (left) and its corresponding small-signal circuit (right). It is noted that the output is shorted to Vpo (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 = gm / (1 + gmRs) In this calculation, the current passing through Rd can be neglected since, in general, Rd is very large when the NMOSFET operates in the saturation region and so this current is very small. Thus, the indication of ia is the current of the voltage-controlled current source (gmVgs) only. Vin + VBIAS

Ascorbic acid (C6H8O6) is readily oxidized according to the half reaction: C6H8O6 + 2 H2O ---> C6H6O6 + 2 H3O+ + 2 e- Potassium iodate (KIO3) dissolved in hydrochloric acid is a typical oxidizing agent used in performing a redox titration of ascorbic acid. a) Write down the reaction equation. As soon as ascorbic acid is totally oxidized, iodine forms, which colors the starch indicator blue and allows for the detection of the end point of the titration. b) Write down the reaction equation for the formation of iodine. To prepare the oxidizing agent, approximately 0.14 g of KIO3 and 3 g of KI are dissolved in 200 cm3 of water, followed by the addition of 20 cm3 of hydrochloric acid (c = 2 mol/dm3). Then, 10.0 cm3 of this solution is titrated with a solution of thiosulfate (c = 0.0100 mol/dm3). The mean value of consumption is 18.6 cm3. c) Calculate the concentration of the potassium iodate solution. Write down the equations for all reactions during the titration. There are 250 cm3 of a solution of ascorbic acid of unknown concentration. 25.0 cm3 of it is transferred to a conical flask. 25 cm3 of hydrochloric acid (c = 2 mol/dm3) and 10 drops of starch solution are added. The mean value of the final volume of the titrant is V = 15.4 cm3 of potassium iodate solution (assuming c(IO3-) = 3.50x10-3 mol/dm3). d) Calculate the mass of ascorbic acid in the total initial solution. V1 and V5 are the volumes of KIO3 solution required for the titration of 25.00 cm3 of the ascorbic acid solution in 1 mol/dm3 and 5 mol/dm3 HCl, respectively. e) Give the mathematical relation between V1 and V5.

Last year, Pizza Hut bought a new commercial oven for the restaurant. Don, the manager, went to another restaurant to see the oven. He was impressed with the cost-efficiency. Upon returning, he asked his purchasing agent to collect price and operating cost data on the oven. He also asked the company's accountant to provide him with cost data on the existing old oven. See this below... Old oven New oven Purchase price $125,400 $179,000 Estimated salvage value $0 $0 Estimated useful life 6 years 5 years Depreciation method Straight-line Straight-line Annual operating expenses other than depreciation: Variable $35,800 $11,700 Fixed $23,000 $9,000 The annual revenues are $239,700 and selling and administrative expenses are $29,500, regardless of which oven is used. If it replaces the old oven now, at the beginning of 2022, Pizza Hut will be able to sell it for $25,000. Determine any gain or loss if the old oven is replaced. If the old oven is replaced, Pizza Hut will incur a profit or loss of $_____. Create a 5-year summarized income statement for each of the following assumptions: I. The old oven is kept. Sales Less costs: Variable operating costs Fixed operating costs Selling and administrative Depreciation Enter a subtotal of the four previous amounts Net income $enter a total amount II. The old oven is replaced. Sales Less costs: Variable operating costs Fixed operating costs Selling and administrative Depreciation Enter a subtotal of the four previous amounts Operating income Enter a total amount for the first part Less: Loss on old oven Net income $enter a total amount Using incremental analysis, determine whether the old oven should be replaced. If an amount reduces the net income, then enter it with a negative sign preceding the number. Retain Old oven Replace Old oven Net Income Increase (Decrease) Variable operating costs Fixed operating costs New oven cost Salvage on the old oven Totals SHOULD THE OLD OVEN BE REPLACED? YES OR NO? _________
