    摘要： A charge pump circuit with resistively attenuated inputs is described herein. By reducing a voltage swing of input signals supplied thereto, the charge pump circuit described herein is configured for producing output signals with relatively low static phase offset even when operating at relatively low power supply voltages (e.g., less than about 1.2 volts). In general, the input voltage swing may be reduced by coupling an attenuator to each input of the charge pump circuit. A method for operating the differential charge pump is described, along with exemplary devices (e.g., PLL and DLL devices) within which the charge pump may be utilized.

    摘要： A bandgap circuit comprising a current generation circuit and a current replication circuit is provided herein. The output current of the current generation circuit is generated as a weighted sum of two currents. The circuit configuration of the current generation circuit allows it to function at low power supply voltages, e.g., on the order of 1 V. The current replication circuit includes an operational amplifier, which when configured in conjunction with MOS cascode current sources and the current generation circuit, significantly increases the accuracy and insensitivity to power supply noise of the bandgap circuit output current. A resistor may be included between the bandgap circuit output node and ground for generating a reference voltage with increased accuracy and insensitivity to power supply noise.

    摘要： Systems and methods improve operation of an applicator that delivers heat-generating energy to an eye as a part of an eye therapy. For example, reflected power may be measured to determine whether sufficient contact has been established between the applicator and the eye for accurate and precise delivery of energy to the eye. In addition, at least one of forward and reflected power may be measured to monitor the application of coolant pulses that control the generation of heat in the eye when the applicator delivers energy to the eye. Further, the forward and reflected power may be measured to determine an efficiency of energy transfer or an impedance mismatch. Based on the efficiency of energy transfer or the impedance mismatch, an adjustable parameter of a tuning element may be modified.
