Switching mode N-order circuit |
摘要 |
A switching mode N-order circuit comprises a first unit, a second unit and a comparator. The first unit includes an operational amplifier integral circuit to integrate a first voltage. The second unit has one or more stages of subunits in cascade each including an operational amplifier integral circuit to integrate a second voltage stage by stage. Each of the operational amplifier integral circuits is equipped with a switch to be controlled by the comparator to be discharged. The output of the N-order circuit is derived from the output of the second unit.
