The figure shows the 1 MHz high-pass filter circuit. This circuit uses high speed current feedback operational amplifier OPA603 with 100MHz bandwidth and 1000V/μs slew rate. It is a second order Butterworth high-pass filter and the corner frequency f0=1/2πRC. Adopting the parameters shown in the figure, f0=1MHz and the circuit gain is 1.6.
