THEORY OF OPERATION
TRANSFER FUNCTION AND ANALOG OUTPUT VOLTAGE
The DecDriver has two regions of operation: where the video
output voltages are either above or below a reference voltage
VMID, and where VMID = (V1 + V2)/2. The transfer function
defines the analog output voltage as the function of the digital
input code as follows:
To best correlate transfer function errors to image artifacts, the
overall accuracy of the DecDriver is defined by two parameters,
VDE and VCME.
VDE , the differential error voltage, measures the difference
between the rms value of the output and the rms value of the

VCME , the common-mode error voltage, measures ? the dc
bias of the output. The defining expression is
