摘要： Some embodiments relate to a level detector, comprising a current mirror including first and second current legs to carry first and second signals, respectively. The first current leg includes a first variable resistor and the second current leg includes a second variable resistor. During a calibration mode, a switching element provides a predetermined reference voltage across first and second control terminals of the first and second variable resistors, respectively. During a non-calibration mode, the switching element decouples the predetermined reference voltage from the first and second control terminals, and provides a signal across the first and second control terminals. Other embodiments are also disclosed.

摘要： A voltage mode driver circuit able to achieve a larger voltage output swing than its supply voltage. The voltage mode driver circuit is supplemented by a current source or “current booster.” The circuit includes a first inverter, a second inverter, and a current source. The first inverter receives a first input and outputs a signal at a node. The second inverter receives a second input signal and outputs an inverted second input signal at the same node. The current source provides current to the node via a first switch, the first switch receiving an input at a first input where the voltage output swing at the node is larger than a power supply voltage applied to the current source. The voltage mode driver circuit uses a stable power supply voltage using a power amplifier with feedback.
