Part Number: OPA615
Tool/software: WEBENCH® Design Tools
Hi -
I am able to implement the integrator circuit using OPA615 but the output is very noisy and has a very low amplitude. Attached is the oscilloscope plot :
ch1 - VG control pulses for the integrator circuit (1.5 MHz)
ch2 - Vin input laser pulses (1.5 MHz)
ch3 - Vout output of the circuit
Is there a way to increase the gain (X20-50 folds) of the output signal and make it less noisy? Are there any trans-impedance amplifiers or filters that could be used?
Best,
Mona
