Abstract

An inexpensive, yet convenient analog storage device was constructed. Sequentially MOSFET-switched 20 sample and holds equipped with a high input impedance preamplifier were parallelly matched to the digitally controlled shift register system in variable speeds up to 3 kHz. To verify its usefulness, square wave train, sinusiodal wave and some electrochemical data, such as fast-scan voltammogram and transient current-time curves of differential pulse polarography were tested.

큰 입력지향을 갖는 20개의 sample and hold가 MOSFET으로 switching되는 간편하면서도 비용이 적게드는 analog 기억장치를 제작하였다. 이것은 digital로 3KHz.까지 임의로 조절되는 shift register로 연결되어 있다. 이 장치의 유용성을 보이기 위해 square와 sine파 및 fast-scan voltammetry와 differential pulse polarography의 전류-시간 변화와 같은 전기화학적 실험을 행하였다.
