Abstract:
Digital to analog converter architectures are disclosed that enable the binary scaling of transistor sized to be replaced by transistors of substantially the same size. This significantly reduced the size of the Digital to Analog converter on a wafer. As the currents from the lesser bits of the converter may be very small indeed, some of the transistors are operated in a regime where the gate-source voltage applied to the transistor is below the threshold voltage for the device, the threshold voltage generally being regarded as marking the onset of significant conduction through a field effect transistor.

Claim (Index 7):
A digital to analog converter as claimed in  claim 5  in which the first transistor configured as a first current source has a degeneration resistor of value 2R (where R is an arbitrary value), and the second transistor configured as a second current source that outputs the second current half that of the first current output by the first transistor and has a source resistance comprised of a first part that is only in a current flow path to the second transistor and has a value 2R and a second part which is in the current flow path with the second transistor and a further load that draws a current equal to the second current passed by the second transistor and has a value of R+(X 1 -2)R, where X 1  selected such that the second transistor carries half the first current of the first transistor.
