Latest Patents

One of Yi Zhao's latest patents is an "Input buffer with selectable hysteresis and speed." This invention provides a signal at an output node based on an input signal. The design includes first and second buffer stages with respective current conduction paths for asserting the output signal. An enabling element selectively activates the second buffer stage in response to an enabling signal, allowing both stages to be enabled simultaneously. The first buffer stage features hysteresis feedback paths that adjust the buffer response, ensuring that the hysteresis is smaller when both stages are active compared to when only the first stage is enabled. Notably, the second buffer stage responds faster to the input signal when enabled.

Another significant patent is the "Self-adapting voltage amplifier and battery charger detection." This amplifier applies a self-adapting voltage to an output terminal, with a bias circuit that provides greater bias current under specific conditions. The circuit can differentiate between the presence and absence of a pull-up resistance connected to the output terminal, allowing it to apply different voltages accordingly. This technology is particularly useful in portable devices that require battery charger detection, complying with the USB battery charger specification rev. 1.2.
