In this paper, we present a flexible ring oscillator IP designed for a 40nm CMOS technology, whose oscillation frequency can be chosen from 200kHz to 20MHz. It was developed using a new design ...

First introduced in the early 1970s, the 555 timer integrated circuit is arguably one of the most popular ICs ever made. Rediscover the iconic 555, how it works and its many uses with the new Book of ...

Internally it’s an extremely simple device, with a trusty 555 oscillator clocking a 4518 counter that in turn feeds 74141 driver. There is a MAX1771 boost converter in there too to create some ...
