A digital/analogue converter for converting an input n-bit digital code,
where n is an integer greater than one, has an n-bit digital input and an
output for connection to a load, and includes: an array of (n-1) switched
capacitors; and a switching arrangement. In one example embodiment, the
switching arrangement is adapted, in a zeroing phase of operation, to
connect a first reference voltage to the first plate of at least one
capacitor of the array and to connect a second plate of the at least one
capacitor to a voltage that, for at least one value of the input digital
code, is different from the first reference voltage and is further
adapted, in a decoding phase of operation, to enable, dependent on the
value of the input digital code, injection of charge into the at least
one capacitor. In one example embodiment, the converter may be a
bufferless converter having an output for direct connection to a
capacitive load.
