I took this a little further, adding a 1.25kHz DABP filter following the Zt stage, it will help your SNR but add complexity. Still staying with +/-5V CMOS op amps there, OPA2743. You can adjust this to single 5V with these parts, or use different parts…
It results netlisting errors when I simulate a simple circuit. I think the circuit doesn't have any problems. And the steps of simulation is correct.
pls help me with the problem, thanks.

The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
