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 19):
A method comprising:\n generating a first current by a first transistor of a plurality of field effect transistors of a digital to analog converter, wherein the first transistor has a first effective transconductance, and wherein the plurality of field effect transistors are configured as current generators and arranged in an array; generating a second current by a second transistor of the plurality of field effect transistors of the digital to analog converter, the second transistor having a second effective transconductance that differs from the first effective transconductance; causing the first and second transistors to operate at sub threshold gate-source voltages such that the first and second currents differ as a function the first and second effective transconducta.nces of the first and second transistors; and associating a resistor with the second transistor to establish a value of the second current generated by the second transistor, the resistor having a resistance value that is based on the second effective transconductance of the second transistor and the first current generated by the first transistor, a value of the first current output being different than the value of the second current output
