ABSTRACT:
Accurate voltage to current converters for rail-sensing current-feedback instrumentation amplifiers using folded cascode transistors. Embodiments using various degrees of cascoding, as well as using bootstrapped folded cascoded input transistors are disclosed. Circuits for sensing around the negative rail are disclosed, though circuits for sensing around the positive rail may be readily achieved by use of complementary devices.
