ABSTRACT:
A circuit (10') and method (50) for digital to analog (D/A) signal conversion. The circuit includes a voltage scaling D/A signal convertor segment (12'), a charge scaling D/A signal convertor segment (14'), and a switch (19) for switching a capacitive load (20') between the voltage and charge scaling D/A signal convertor segments (12',14'). The method includes converting (52,54,56) digital input signals to partial and final analog output signals, and applying (58) a partial analog output signal to the capacitive load (20') before applying (60) the final analog output signal to the capacitive load (20').
