Therefore, the output voltage waveform is a ramp function. 3. Find R1 and RF in the lossy integrator so that the peak gain and the gain down from its peak is 40db to 6db. Assume ω=20,000 rad/s and capacitance = 0.47µF.
A. R1 = 10.6Ω, RF = 106Ω
B. R1 = 21.2Ω, RF = 212.6Ω
C. R1 = 42.4Ω, RF = 424Ω
D. R1 = 29.8Ω, RF = 298Ω
Answer:A
