I am having a bit of trouble with designing a regulated power supply for a measurement system. I have access to a 12V battery and require a
+- 10V supply (for all my op-amps). I have designed the measurement system around a maximum voltage regulation error of +- 10 %, so I dont need a fantastic design, just one that can meet these specs.
Just in case you want to know the measurement system is designed to measure the wear of a brake disc on, for example, a formula one car. The system comprises of an oscillator and amplifier driving an LVDT, with each of the secondary outputs of the LVDT being rectified by a precision rectification stage. These two rectified signals are then put through an instrumentation amplifier, an anti-aliasing filter and then fed into the ADC of a microcontroller.
I'd appreciate any feedback. Thanks!!
