7400 competition entry: Using two CD4007 IC as an op amp to generate sine waves

in 7400 contest, contest by DP | 0 comments

Here’s an interesting way of designing analog devices using digital chips. This sine wave generator s based around mosfets contained in the CD4007 IC (a dual complementary pair of mosfets and an inverter). The CD4007 dual complementary pair and inverter is primarily … Read more
