The cost of building a system on chip at lower geometries like 65 or 45 nanometer is very high. This is becoming a major impediment for investors to invest in such products. ‘Green Technology’ is the buzzword of the day. We are already seeing investments chasing anything that is green. There are huge opportunities for the development of products which consume less energy. And once alternative energy applications become main stream we will naturally need analog chips to drive them. Traditionally analog chips have been built by companies that have in-house fab capabilities. The shift towards building analog chips in a fabless model has begun only recently. This translates to opportunities for startups. However, one needs to keep in mind that hiring good analog designers has always been a challenge. This makes it harder for the startups to make an entry.
