OTTAWA, ON and SANTA CLARA, CA - Sidense has released a white paper, "Optimizing Sensor Performance with 1T-OTP Trimming," discussing the advantages of using antifuse-based one-transistor, one-time programmable (1T-OTP) memory to trim sensors.
Variations in component and circuit characteristics, along with chip processing and packaging operations, result in deviations of analog circuits and sensors from their target specifications. To optimize the performance of the systems in which these components are placed, it is necessary to "trim" interface circuitry to match a specific analog circuit or sensor. A 1T-OTP based trimming operation compensates for variations in the analog circuits and sensors due to manufacturing variances of these components.
