摘要： A track-and-hold circuit includes an input stage (IS), an output stage (OS) and a switching stage (SS). The switching stage is coupled between the input stage and the output stage. The switching stage includes a switching transistor (T10), a differential amplifier (T11/T12), a current source (T13/R11), and a capacitor (C11). In order to improve the frequency response, the input stage is provided with a passive impedance coupled between a base of the switching transistor and a first supply terminal (1) and the input stage is adapted to supply a signal current to the base of the switching transistor. This signal current is related to an input signal applied to the input stage. The output stage includes a first output transistor (T14), a first current source (T15) switched by a tracking signal (Vt), a second output transistor (T16), and a second current source.

摘要： A differential voltage-current converter has two input transistors and two cross-coupled transistors arranged in a translinear loop, the difference voltage across the emitter resistors of the cross-coupled transistors being equal to the difference voltage across the input terminals. The difference current through the cross-coupled transistors is replicated in the output transistors, thereby enabling a larger output signal amplitude to be obtained. In order to increase the permissible input voltage the bases of the cross-coupled transistors are coupled to the input transistors via emitter-followers. By connecting the collectors of the emitter-followers to the collectors of the output transistors a compensation is obtained for the decreasing current gain at high frequencies.

摘要： A differential amplifier comprises two input transistors and two cross-coupled transistors arranged in a translinear loop. A difference voltage across a resistance connected between the emitters of the cross-coupled transistors is equal to a difference voltage across the input terminals plus the sum of the offset voltages across resistors arranged in series with the respective emitters of the input transistors. The difference current through the cross-coupled transistors is replicated in output transistors, thereby producing an output signal amplitude larger than the input signal amplitude across a resistance coupled between the emitters of the output transistors. The differential amplifier is suitable, inter alia, as an interpolating residue signal amplifier with additional underflow and overflow ranges in multi-step dual-residue analog-to-digital converters.

A wireless power transfer system includes features that allow the system to be deployed in public spaces such as airports or in commercial establishments such as restaurants or hotels to allow a user to recharge one or more portable electronic devices while away from home. To accommodate wireless recharging of a variety of device types and states, the system may receive parameters and/or state information associated with a portable electronic device to be recharged and may control the wireless power transfer in accordance with such parameters and/or state information. For instance, the system may increase efficiency of the wireless power transfer based on such parameters and/or state information. The system may also provide a secure and efficient means for obtaining required payment information from the user prior to the wireless power transfer, thereby facilitating fee-based recharging.
