Term
 Ideal Op-Amp
Definition
 Infinite GainZero Output ImpedanceInfinite Input ImpedanceNo current into the + and - terminalsZero Offset Voltage (V+ + V- = 0)
Term
 Clipping
Definition
 Output voltage cannot exceed the rail voltage (supply voltage)
Term
 Voltage across a capacitor
Definition
 V = Q/C
Term
 Non-Inverting Gain
Definition
 Vout = (1+(Rf/Ri))*Vin
Term
 inverting Gain
Definition
 -(Rf/Ri)*Vin
Term
 Differential Amplifier Gain
Definition
 ((R1 + R2)/(R3+R4))*(R4/R1)*V2 -(R2/R1)*V1
Term
 Instrumentation Op-Amp
Definition
 Differential Amplifier with variable gain
Term
 Voltage Follower
Definition
 Op Amp used as a buffer, feeding Vout back to the V- terminal giving Vout = Vin
Term
 Summing Amplifier
Definition
 Non-inverting and Inverting. Uses multiple resistors to create a summing effect at the V+ terminal (Vout may or may not have one)
Term
 Capacitor Impedance
Definition
 R(s) = V(s)/i(s) = 1/Csequivalent resistor valueR(jw) = 1/jCw
Term
 Angular Frequency (Cutoff)
Definition
 wc = 2*pi*fc
Term
 1st Order Low-Pass Filter Cut-off Frequency
Definition
 fc = 1/(2*pi*R*C)
Term
 Audio amplifier
Definition
 Op-Amp transition between Voltage Follower to Amplifier as a function of frequencyNon-inverting Op-Amp with Ri replaced with Ri and C
Term
 High Frequency Gain
Definition
 Determined by taking the limit as s -> inf.
Term
 Low Frequency Gain
Definition
 From Fourier Analysis of circuit behavior, letting s=jw and w = 0
Term
 2nd Order Butterworth Filter
Definition
 Low pass, well damped filter
