Abstract :
This paper presents a CMOS circuit implementation of a spike event coding/decoding scheme for transmission of analog signals in a programmable analog array. This scheme uses spikes for a time representation of analog signals. No spikes are transmitted using this scheme when signals are constant, leading to low power dissipation and traffic reduction in a shared channel. A proof-of-concept chip was designed in a 0.35 mum process and experimental results are presented.
