- Slammed on brakes and car shut off,operational amplifiers (Op-Amps). In addition, high-frequency amplifiers should be impedance matched on their input and output. However in the audio band, impedance matching is not a concern. Due to the low frequency range the audio band covers, either Op-Amps or transistors can be used, although the implementation here was Op-Amp based. ,• Input impedance The input impedance of the common emitter amp can be calculated from the following equivalent circuit: Vin R1 R2 Rtin 1 Rin = 1 R1 + 1 R2 + 1 Rtin Rtinª DVB DIB = DVE DIE /b = DIERE DIE /b = bRE For AC case R1 and R2 are usually > Rtin so the input impedance is given by Rtin= bRE = brBE = 2500 W for 1 mA of collector current and b = 100. • Output impedance
