I am working on current to frequency converter which consists of following two circuits
1- Integrator circuit which integrates the current. In the beginning output of this stage is RESET to ground (0V) and then because of current integration, output of integrator starts rising.
2- Output of integrator goes to a comparator which compares this voltage with a reference voltage and as soon as output of integrator becomes equal to this reference, comparator output toggles and RESET the integrator.
What I see is very high level of noise at low frequencies. Can someone please suggest some reference for understanding the root cause of this type of noise better.
Any suggestion/comment with be very useful.
Thanks, Raj
