Zusammenfassung:Delta - Sigma analog-digital converters based on SC delay and SC differentiators are proposed and constructed. Novel Delta - Sigma analog-digital converters can also be incorporated with SC integrators to implement Delta - Sigma analog-digital converters with more design flexibility and freedom. Novel SC differentiators and SC delay which do not require a high slew rate op-amp are also described. A design example of a one-bit second-order Delta - Sigma analog-digital converter is given. Good performance of simulation responses confirms the correct operation of the proposed structure.< >
