Abstract

In this paper we present a switched current based macrocell block dedicated for field programmable analogue arrays. The macrocell uses a combination of class A switched current cells performing programmable basic analogue signal processing multifunction. In fact, by means of a set of static switches it allows us to configure basic linear discrete time functions such as lossless and damped integrators and differentiators. The proposed macrocell gets profit from the flexibility of switched current techniques implementing programmable filters, oscillators, control systems, and both ADC and DAC blocks. The present work highlights the main idea and a validation of the planned functions. Simulation results are presented showing the functionality of some examples.
