3E Problem 1. (P1) Three op-amps are connected in cascade configuration. An 80 microVolts signal is connected to the non-inverting input of the first op- amp. Both the 2nd and 3rd op-amps operates as inverting amplifiers. All feedback resistors are 420 KOhms while the input resistances are 71.4kOhms, 19.1kOhms, and 14kOhms respectively. Determine the input voltage of the second stage stage. O a. 1.2 mV O b. 1.2 V O c. 1200 mV O d. 12 V
