Classification: CPC H  G | IPC G  H

Claim 8:
9. A compensation circuit according to claim 8, wherein the voltage divider circuitry and the amplifier circuitry constitute a digital to analogue converter (DAC), wherein:
the resistance values of the selectable resistances of each array are weighted such that an input-output characteristic of the DAC is non-monotonic; or
the resistance values of the selectable resistances of each array are weighted such that for a given bias voltage, a particular DAC output value can be produced by a plurality of different combinations of selectable resistances of the first, second and third arrays; or
the resistance values of the selectable resistances of each array are weighted so as to produce a plurality of overlapping DAC output signal ranges.
