Term
Differential Amplifier Gain 

Definition
((R1 + R2)/(R3+R4))*(R4/R1)*V2 (R2/R1)*V1 


Term

Definition
Differential Amplifier with variable gain 


Term

Definition
Op Amp used as a buffer, feeding Vout back to the V terminal giving Vout = Vin 


Term

Definition
Noninverting and Inverting. Uses multiple resistors to create a summing effect at the V+ terminal (Vout may or may not have one) 


Term

Definition
R(s) = V(s)/i(s) = 1/Cs
equivalent resistor value R(jw) = 1/jCw 


Term

Term

Definition
OpAmp transition between Voltage Follower to Amplifier as a function of frequency
Noninverting OpAmp with Ri replaced with Ri and C 


Term

Definition
Determined by taking the limit as s > inf. 


Term

Definition
From Fourier Analysis of circuit behavior, letting s=jw and w = 0
