Microelectric Circuits 25

Please check my work and if incorrect give me the correct answer 25 Consider an op-amp having a single-pole open-loop response with Ao = 104 and fp = 10 Hz. Let the op-amp be ideal otherwise (infinite input impedance, zero output impedance, and so on). If this amplifier is connected in the noninverting configuration with a nominal low-frequency closed-loop gain of 80, find the frequency at which |A times beta| = 1. a. 1.25 kHz b. 2.5 kHz c. 5.0 kHz d. 10 kHz My solution is: A0=10^4 fp=10Hz A=80 A*Beta=1 F=A0*1=10000 or 10kHz Answer is D

Logic

Realize the following function using only two-input NAND gates. See attachment for function. I do not understand how i would get this with NAND gates? Please draw out so i can see.

Electronic problems

Hi I hope you can help me with these few questions, I have made some attempts myself. On question 1 I have assumed a supply voltage of 28volts. That is If this is what the question means. The text book is HUGHES electrical and electronic technology (1) A zener diode has a reverse breakdown voltage of 14V with a maximum load current of 70mA calculate a suitable value of limiting resistance L Res = VIN - ZD1 L Res = 28V - 14V = 200 ohms IZD1 70 mA (2) In a stabilisation circuit if the internal resistance is 8 ohms and the load current change is 60mA what is the value of Vs This is in ... click for more
