Helping neuromorphic sensors leave the designer ’ s desk

A variety of impressive neuromorphic sensors have been developed over the years, but hardly any have so far made it into applications outside carefully-controlled laboratory setups. Even when on the designer’s desk, most neuromorphic sensors only operate well under tightly-controlled bias settings that require much experience and patience in twiddling potentiometers. To change this, we recently developed the sensor-control-interface board1 (SCI). This provides a small and inexpensive microprocessor-controlled ‘mobile laboratory environment’ optimized for the low-noise operation of analog VLSI circuits. Tuning and operation of chips in this environment is simpler and faster than previous procedures, because the sensor setup and data recording is managed by PC. Additionally, the SCI can operate as a mobile stand-alone board, providing a variety of control signals for real-world systems such as small robots.
