Method and apparatus for dynamically biasing switching elements in current-steering DAC
摘要:
A circuit dynamically biases switching elements in a current-steering digital-to-analog converter (DAC), The DAC includes, in each cell, a current source coupled to a current node, a first switching element coupled between the current node and a first DAC output node, and a second switching element coupled between the current node and a second DAC output node. The circuit includes first and second inputs coupled to the first and second DAC output nodes, respectively, first and second outputs coupled to the first and second switching elements, respectively, and a third output coupled to the first and second switching elements. The first and second outputs provide a first ON bias voltage and a second ON bias voltage to control the first and second switching elements, respectively, such that a voltage at the current node is maintained at a predetermined voltage. The third output provides a common OFF bias voltage.
