Complementary-MOS Low-Power Low-Voltage Integrated Binary Counter

In May 1962, Dr. Eric Vittoz was the first electrical engineer hired by Centre Electronique Horloger (CEH), the research laboratory founded in Neuchatel, Switzerland by several organizations representing most of the Swiss watch industry. This paper represents Dr. Vittoz´s early work there on an integrated complementary MOS-transistor binary counter stage realized in monolithic form, which allowed p-channel and n-channel MOSTs to be grouped together within two distinct surface areas, resulting in a reduction of the surface necessary for given circuit functions. The integrated frequency divider was used in the first prototypes of electronic watches.
