Abstract
A circuit samples a voltage on a simultaneous bi-directional bus, and subtracts an outbound voltage to determine an inbound voltage. Sampling capacitors are variable to adjust for matching time constants. A mechanism is provided to sample error voltages over clock phase variations and sampling capacitor values.
