Stochastic pulse coded arithmetic
(IEEE, 1999)
Among the different pulse codification techniques, stochastic pulse codification has its own arithmetic based on the similarity between Boolean algebra and statistical algebra. Summation and multiplication are the two ...

An analog CMOS universal membership function circuit with fully independent, adjustable parameters
(1997)
A novel CMOS membership function circuit (MBC) is presented. It is based on a linear tunable transconductor proposed in [1] and implements trapezoidal/triangular functions with all parameters (slope, position, width, eight ...

Analog controllers using digital stochastic logic
(1999)
Stochastic logic is based on digital processing of a random pulse stream, where the information is codified as the probability of a high level in a finite sequence. The probability of the pulse stream codifies a continuous ...

CMOS fuzzifier using mixed-signal techniques with emphasis in power consumption
(1999)
A novel mixed-signal CMOS membership function generator (MFG) is presented. It is based on an enhanced version of a linear tunable transconductor proposed in [1] and implements trapezoidal/triangular functions with all ...
