Abstract: One or more layout techniques may be used to balance a current sense circuit. The current sense circuit may include upstairs resistors for an amplifier which are formed of polysilicon material. The upstairs resistors may be arranged symmetrically about one or more stress gradients for improving an accuracy of the current sense circuit. The stress gradients may include stress gradients about an axis and stress gradients from a die edge.

Abstract: An integrated circuit for measuring current while receiving wireless power is described. The integrated circuit measures a current across a resistor by an amplifier. A gain of the amplifier is based on a pair of matched upstairs resistors and a pair of matched downstairs resistors. The pair of matched upstairs resistors may include an offset in resistance. The integrated circuit includes a switch matrix with switches coupled between the integrated resistor and the pair of matched upstairs resistors. The offset for the pair of matched upstairs resistors may be measured by selectively controlling the switches.

Abstract: A structure is described which includes two amplifiers in parallel. A first amplifier is considered an always-on amplifier. The always on amplifier provides continual measurements of a current (Isns) across an integrated polysilicon resistor for one or more analog control loops. A second amplifier is considered a switched amplifier. The switched amplifier provides measurements of the current (Isns) for one or more digital control loops. The switched amplifier is switched by one or more switches for performing offset measurements with high accuracy.

Abstract: A converter includes a first circuit. The first circuit includes a first input that receives a power supply signal, a second input that receives a first signal, and a first output that outputs a second signal having an amplitude that is based on a frequency of the first signal. The first signal is based on an error value and a third signal, and the third signal is independent of feedback of the first circuit. The converter also includes a second circuit having a second output coupled to the second input and that outputs the third signal. The second circuit nonlinearly adapts the third signal based on the power supply signal and a reference signal.

Abstract: A hysteretic switching regulator with low output ripple voltage is disclosed herein. A detector and controller is specifically used to adjust a parameter of the hysteretic switching regulator to compensate for changes in one or more of input voltage and desired output voltage to maintain the output ripple voltage within some desired range.

Abstract: A current-mode peak detector circuit is disclosed. The current-mode peak detector circuit includes an input transistor for receiving an input current that impresses a voltage on a control node, a pair of transistors for providing an output current in response to the voltage at the control node, and a decay control circuit for controlling the decay of the voltage at the control node such that the output current is representative of a peak value of the input current signal. A clamp circuit may be provided for clamping the input voltage to a predetermined level. All of the elements of the current-mode peak detector circuit may be realized using transistors for facilitating integration of the current-mode peak detector circuit on an integrated circuit. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other researcher to quickly ascertain the subject matter of the technical disclosure.
