Latest Patents

Kaneta's latest patents include an envelope tracking power supply circuit and a high-frequency amplifier that incorporates this power supply circuit. The envelope tracking power supply circuit is designed to generate an output voltage that corresponds to the envelope of a high-frequency signal. It features a voltage follower circuit that receives an envelope signal and outputs a voltage based on that signal. Additionally, it includes two parallel resistors connected between the output of the voltage follower circuit and an output terminal, along with hysteresis comparators that detect voltage drops in the resistors. The circuit also utilizes switching converters to output a voltage to the output terminal.

Another significant patent is the time-to-digital converter (TDC) circuit, which is characterized by its small scale and high resolution. This TDC detects the phase of a signal relative to a reference clock. It comprises a first delay line with multiple delay elements connected in series, and a second delay line group that connects to the first delay line's nodes. The circuit includes judgment circuits that determine whether the signal's changing edge is advanced or delayed compared to the delayed clock output. The operation circuit then calculates the phase based on these judgments.
