Hi.....
I have designed and fabricated a 16Bit second order, single bit sigma delta modulator based ADC. During testing of ADC, when we apply zero volt at the input of ADC, sometimes it works fine and sometimes it gives a fixed code of 00FF (hex). Otherwise the ADC is working fine. Are these limit cycles and what is the solution?
