Differentiator Circuit Calculator
Calculate parameters for an op-amp differentiator circuit.
Circuit Parameters
Results
100.00 us
Time Constant (RC)
1.59 kHz
Corner Frequency
-24.0 dB
Gain at Frequency
+90°
Phase Lead
Output Voltage
Sine Wave Output (peak)0.0628 V
Square Output (from triangle)0.0400 V
Voltage Gain (V/V)0.0628
Design Considerations
Max Recommended Freq15.92 kHz
Warning: Differentiators amplify high-frequency noise. Add a small resistor in series with C to limit HF gain.
Formula
Vout = -RC * d(Vin)/dt
Sine in produces cosine out (90° phase lead). Triangle wave in produces square wave out.
