In this paper, a technique for local biasing of analog VLSI operator circuits has been discussed. The circuit we refer to is an exponential operator: we designed a bias circuit which locally generates the bias voltage for such operator, compensating for technological process gradients. Theoretical background, circuit implementation and simulation results are presented and discussed.

Abstract
In this paper, a technique for local biasing of analog VLSI operator circuits has been discussed. The circuit we refer to is an exponential operator: we designed a bias circuit which locally generates the bias voltage for such operator, compensating for technological process gradients. Theoretical background, circuit implementation and simulation results are presented and discussed.File in questo prodotto:
