Paleo diet macros D1

5.6K? 1K? b) Consider the following circuit with ideal op?amp (output saturation levels of ±12V). Weight loss recipes app Use constant voltage drop model for the diodes (VD(ON)=0.7V) to find v_, vA, and vo for: i. Diet plan after pregnancy v1=+1V ii. Lose weight fast diet tips v1=+2V iii. Paleo hamburger recipes v1=?1V iv. Exercise induced anaphylaxis v1=?2V Page 2 of 22 Final Exam April 2010 ECSE330 Page 3 of 22 Final Exam April 2010 ECSE330 Page 4 of 22 Final Exam April 2010 ECSE330 Page 5 of 22 Question 2 (10 marks) Final Exam April 2010 ECSE330 The above circuit is a current amplifier where the input is the current i1 and the output is the current iL in the load RL. Paleo diet chicken recipes Assuming the op amp to be ideal, it is required to design the circuit shown above to implement a current amplifier with gain iL/i1 = 10 A/A a) Find the required value for R. Losing weight through diet b) What are the input and output resistances of this current amplifier? c) If RL = 1 k and the op amp operates in an ideal manner as long as vo is in the range of ±12V, what range of i1 is possible? d) If the amplifier is fed with a current source having a current of 0.2 mA and a source resistance of 10 k, find iL.

Exercise science careers Assume VDD = 5 V, ?VSS = ?5 V, RS3 = 5 K?, ?nCOX = ?pCOX = 200 ?A/V2, Vtn = |Vtp|= 0.5 V, and (W/L)= 10 for all transistors. Paleo diet lunch ideas You may ignore channel length modulation and body effect. Lose weight fast workout Also assume that all transistors are supposed to operate in saturation mode. Weight loss vegetable soup For the Above amplifier circuit assume that the capacitors are infinitely large capacitors and that RS = 50 ? and RL = 5 K?. Healthy diet smoothies a) The above circuit is a multistage amplifier. Paleo diet debunked Identify each amplifier section and indicate its type (CG, CS or CC). Exercise is medicine month b) Bias the amplifier above (choose R1,R2, RC and RD2) such that ID1= ID2= ID3=1mA and Rin1=100K?±10%. Weight loss tips for women c) Draw the small?signal equivalent circuit of the amplifier. Paleo fast food d) Calculate the small?signal parameters gm1, gm2, and gm3 of the transistors M1, M2, and M3 based on the bias conditions established in b). Healthy diet when pregnant e) Derive expressions for the small?signal input impedances Rin1, Rin2, and Rin3 as a function of the resistor values and transistor small signal parameters, then calculate their numerical values. Exercise guidelines for older adults f) Derive expressions for the small signal voltage gains vin/vs, vo1/vin , vo2/vo1, and vout/vo2 a function of the resistor values and transistor small signal parameters and calculate their numerical values. Qigong exercises for eyes g) What is the maximum output voltage swing? (assuming that, with the constant gain found in part g, you can adjust the magnitude of the input signal to get a desired output voltage) Page 9 of 22 Final Exam April 2010 ECSE330 Page 10 of 22 Final Exam April 2010 ECSE330 Page 11 of 22 Final Exam April 2010 ECSE330 Page 12 of 22 Final Exam April 2010 ECSE330 Page 13 of 22 Question 4 (15Marks) Final Exam April 2010 ECSE330 For the amplifier circuit above use R1=R2=200K and =100 for all transistors. Weight loss quit drinking For dc analysis,

you can assume infinite . Weight loss on paleo Ignore the Early effect for all computations. Paleo diet gluten free a) The amplifier above is a three stage amplifier. Paleo chicken Identify the type of each stage, and lable

b) Select the values of R3, R5, R6, R7 such that all transistors operate in the active mode
