Abstract

In this work two multistable circuits suitable for analog memories implementation will be presented. These circuits have been used to implement completely asynchronous analog memories, one type based on a flash converter and thus having a linear complexity in resolution; the other based on an asynchronous successive approximation converter and thus having a logarithmic complexity in resolution.Experimental results from measurements over prototype chips will be shown and analyzed, and connections with design choiches highlighted.
