A novel SC (Switched-Capacitor) offset- and gain-compensated sample/hold circuit is presented. It is implemented by a new topology which reduces the effects due to the imperfections of op-amp. Simulation results indicate that the circuit achieves high accuracy without requiring high-quality components.

This paper introduces a switched-voltage delay cell with differential inputs. It can be used as a building block for a range of analogue functions such as voltage-to-frenquency converter, A/D converter, etc. Applications incorporating the delay cell are presented. The performances are verified by simulations on PSpice.
