Hi, I am totally unfamiliar with regards to simulating electrical circuit and quite lost on proceeding.
I am thinking of using the ngspice features in kicad to simulate the circuit response.
The attached picture is the schematics of a circuit board I have that is suppose to be able to supply a steady current within nano-ampere range to a 100M ohm thermistor on the left hand side of circuit. The right is the circuit is connected to a 12 voltage power supply and ground. However I am totally stuck on how to simulate the expected current/voltage on the left hand side.
Would appreciate any advice how I can get this simulate properly. It is an old design where I have already the circuit itself physically. It is just that I am unable to test it therefore would love to use simulation to verify its functionality.
