Abstract :
A new cyclic digital-to-analog converter using integrator-type sample and hold (S/H) circuits is described. The converter is capable of achieving very high-resolution and very-high accuracy conversion without requiring a precision weighted network. It does not suffer from the problems of stability, switch charge injection, etc. If a high degree of linearity is desired, trimming is necessary. The trimming process is as simple as in the case of gain error or zero error trimming
