- Figure 1. Op-amp A1 continuously integrates the incoming VIN signal, thus minimizing noise. Conversion occurs in alternating phases, T- and T+. The T-/T+ phase duration ratio is independent of the RC time constant, is therefore insensitive to C1 toleranc
- Figure 2. Various conversion signals found at circuit nodes X, Y, and Z
- Figure 3. Black = VIN, Red = T+ duration in ms, Blue = T- duration, C1 = 0.001 µF
