Low-Voltage MOS Translinear Analog Signal Processing

Different design procedures to operate MOS translinear loops at low supply voltage are presented. They utilize innovative biasing strategies based on flipped voltage followers and floating batteries. An alternate topology based on coupled negative feedback loops is also introduced. Simulation and measurement results for various test chip prototypes validate the proposed techniques and allow comparison among them.
