Question

Complete the following at a time determined by the laboratory instructor. Given the parameters of the first model, Ri Ro, and Av, determine formulas for Gm, Rm, and A, in terms of the given parameters. Amplifier design Compute resistor value R1 to give the circuit below a voltage gain of (-x). The variable x may vary among lab teams and will be provided by the instructor. Unless directed otherwise let x = 10. Round resistor value R1 (if necessary) to the nearest value in the standard 12-point logarithmic sequence shown in table 1. Using the rounded value of R1, compute R3 and round its value accordingly. Enter the National Semiconductor website, www.national.com. and retrieve the data sheet for a LM741 op-amp. Print out the pages that show the package connection diagrams, the absolute maximum ratings, and the electrical characteristics.

Explanation / Answer

GAIN (AV) = -R2 / R1 voltage gain = -10 R1 = -10/-R2 = 10/10K = 1/1000 after inverting we got R2 = 1K(standard)
