WEEK 15: FINAL CORRECTING DEVICES: AMPLIFIERS Sections: Basic | Circuits | Op-Amps Definition. A circuit whose output is proportional to how long the input has been present.
1. If VIN just recently appeared, IRin and IC are not flowing for very long, therefore: VC = VOUT. When VC is small, VOUT is also small. 2. If VIN is present for some time, t, the capacitor will charge for the same time, t, and VC is a considerable voltage. Thus, VOUT will also be considerable. 3. If VIN is present for a longer time, t, the capacitor will charge fully, and VC is the full voltgae. Thus, VOUT will be very large. Therefore, in an Integrator Op-amps, the presence of VIN equates to the magnitude of VOUT. Voltage-to-Current Op-Amps |
