Advances in manufacturing technologies of CMOS integrated circuits have enabled obtaining the shrinkage of the device dimensions together with higher working frequencies at the expense of a greater dispersion in their characteristics. The impact of process variations specially affects the performance specifications of the analog and RF sections.
The main objective of this project is to develop design methods that allow to construct inherently robust circuits against manufacturing process variations. We intend to approach the problem from previous results already obtained by our group in predictive test. This test strategy consists in estimating the circuit performance parameters from indirect measurements, an approach easier to implement than by means of the standard methods.
The proposed solution consists, first, in implementing the elements to carry out the test process on the own chip; this is the well-known Built in Self Test technique. Then, the results of the predictive test are used to modify, either the value of a circuit element or the own structure of the circuit, with the aim of optimizing some of their performance specifications. Hence, self-adjustable or reconfigurable circuits are obtained.
Although the concept can be applied to any anlog circuit, its implementation has to be tailored for each kind of circuits. Initially it will be applied to two circuits: a low pass filter for a RF receiver (self-tuning) and a pipeline analog to digital converter (reconfiguration). Nevertheless, all through the project we will seek new objective circuits.
