| 20120133539 | Comparator Circuit - An analog-to-digital converter includes a comparator configured to receive a first input signal and a second input signal, in which at least one of the input signals is received between two transistors, each of the transistors being in common-gate configuration. | 05-31-2012 |
| 20120032829 | DIGITAL-TO-ANALOG CONVERTER WITH CODE INDEPENDENT OUTPUT CAPACITANCE - A Digital-to-Analog Converter (DAC) with code independent output capacitance includes circuitry configured to convert a digital input signal to an analog output signal in a manner such that at least one output terminal of the DAC exhibits a constant capacitance value for up to all received values of the digital input signal. A method for converting a digital signal to an analog signal with a DAC includes converting a digital input signal to an analog output signal in a manner such that at least one output terminal of the DAC exhibits a constant capacitance value for up to all received values of the digital input signal. | 02-09-2012 |
| 20110279133 | Electric Current Measurement - A method for measuring electric current applied to a load includes: with a sensor element having an inaccuracy, measuring an electric current supplied to a load to produce a measurement of the electric current; with the sensor element, measuring the electric current with an added perturbation current; and using measurements of the electric current taken with and without the perturbation current to refine the measurement of the electric current. | 11-17-2011 |
| 20100321227 | Current Mode Analog-to-Digital Converter - A current-mode analog-to-digital converter includes: a current input node; a current-mode sample and hold circuit configured to output a steady source of electrical current having an analog value proportional to a sampled analog value of an electrical current at the current input node; and at least one current comparator that compares the electrical current output by the current-mode sample and hold circuit to at least one reference current to produce a digital representation of the sampled analog value of the electrical current at the current input node. | 12-23-2010 |
| 20100295714 | Pipelined Analog-to-Digital Converter - A pipelined Analog-to-Digital Converter (ADC) comprising a number of stages, at least one of the stages includes a sample and hold circuit. The sample and hold circuit includes a first output connected to an input of a sub-ADC, an output of the sub-ADC connected to an input of a Digital-to-Analog Converter (DAC), an output of the DAC connected to a node, and a second output connected to the node. The sample and hold circuit is configured to independently scale a signal produced by the first output and a signal produced by the second output. | 11-25-2010 |
