Increasing analog programmability in SoCs

The use of programmability in systems-on-chip (SoC) brings as the main advantage the possibility of reducing the time-to-market and the cost of design, specially when different systems and functions must cover different markets, going from low-power and low-frequency instrumentation to high frequency communication. This paper presents a technique that can be used to increase the analog programmability in a SoC, also allowing one to integrate more analog functions, while guaranteeing the use of the analog part in a larger range of applications. Practical results are presented showing that the proposed technique can be used from DC to RF applications
