Abstract :
A novel circuit is described that produces a sigmoidal neuron transfer function for a pulse-stream neural network. The input activation is represented by a voltage and the output by the time between pulses. The circuit has been implemented as an ASIC using BiCMOS technology and utilises 17 MOSFETs. Simulation results show that the neuron has excellent correspondence with the desired sigmoidal transfer function. In addition, the circuit has good temperature stability and small size, occupying only 600×150 μm
