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 26):
A digital to analog converter comprising:\n a power supply line; and. a plurality of field effect transistors configured as current generators and arranged in an array, wherein:\n a first transistor of the plurality of field effect transistors has a first effective transconductance and outputs a first current of an amount that differs from a second current output by a second transistor of the plurality of field effect transistors having a second effective transconductance that differs from the first effective transconductance, \n a resistor component, separate from the power supply line, the resistor component being coupled between the power supply line and a terminal of the second transistor; and \n the first and second transistors are operated at sub threshold gate-source voltages such that the first and second currents differ as a function the first and second effective transconductances of the first and second transistors.
