Comparison between CMOS and TTL Logic - Which is Better and Why? It might be surprising to know that the patent for a ‘field effect transistor’ predated the creation of the bipolar transistor by at least twenty years. However, bipolar transistors were quicker to catch on commercially, with the first chip made of bipolar transistors appearing in the 1960s, with MOSFET manufacturing technology being perfected in the 1980s and soon… |
