Parasitic compensated switched capacitor circuits

A parasitic-insensitive switched capacitor circuit is presented which can functionally replace the `toggle-switched? capacitor. Its properties are established via an inverting integrator application. A related parasitic-insensitive realisation is also shown for a noninverting integrator, which can provide a 3/2 clock period transmission delay.
