Bipolar/CMOS current-source flip-flop for application in neuro-fuzzy systems

A new current source flip-flop is presented which delivers an analogue current according to the state it stores. To enhance precision the output current is delivered while the main transistors are biased as CMOS compatible lateral bipolars. For reading and writing, these transistors are biased as regular MOS transistors. The resulting cell is extremely compact, allows low-voltage operation and is useful for neural and fuzzy based mixed mode processing systems
