Delay adjustment circuits
Methods, systems, and devices for delay adjustment circuits are described. Amplifiers (e.g., differential amplifiers) may act like variable capacitors (e.g., due to the Miller-effect) to control delays of signals between buffer (e.g., re-driver) stages. The gains of the amplifiers may be adjusted by adjusting the currents through the amplifiers, which may change the apparent capacitances seen by the signal line (due to the Miller-effect). The capacitance of each amplifier may be the intrinsic capacitance of input transistors that make up the amplifier, or may be a discrete capacitor. In some examples, two differential stages may be inserted on a four-phase clocking system (e.g., one on 0 and 180 phases, the other on 90 and 270 phases), and may be controlled differentially to control phase-to-phase delay. |

Coordinating voltage and frequency changes in wireless power transfer
A wireless transmitter coordinates changes in the transmitter's input or output voltages with changes in the transmitter's operating frequency to counteract the transmitter's output power changes while changing the voltages. When the voltages are being increased, the output frequency is moved away from the resonant frequency. Consequently, the output power increase due to the increased voltages is restrained by the frequency change. Before or after the voltage increase, increased output power can be obtained by changing the output frequency while the input and output voltages are held constant or near constant. Some embodiments follow similar procedures when reducing the transmitter's input or output voltages. Calibration is performed before power transfer to determine suitable voltage and frequency profiles for voltage change operations. Other features are also provided. |
