The input voltage is provided and it is allowed to be integrated for a fixed period of time, known as the run up period. Due to this essential role, ADC circuits have been well studied over 40 years, and many problems associated with them have already been solved. An integrator is a relatively simple op amp-based circuit. The design of delta-sigma ( DS) analog-to- digital converters (ADCs) is approximately three-quarters digital and one-quarter analog.
