Latest Patents

One of Ng's latest patents is a single-power-transistor battery-charging circuit that utilizes a voltage-boosted clock. This invention features a charge/discharge protection circuit that safeguards a battery from inadvertent shorting on a charger node. The design includes a single n-channel power transistor, which is controlled by a gate that manages the connection between the battery and the charger node. The gate is linked to the charger node via a gate-coupling transistor, ensuring battery isolation. The circuit is driven by a voltage-boosted clock, activated by an enable signal, which also engages a grounding transistor to ground the gate of the gate-coupling transistor.

Another notable patent addresses ESD protection using a capacitively-coupled clamp. This circuit is designed to protect low-voltage core transistors from high-voltage outputs. It connects an internal node to the gate of an n-channel output transistor, grounding it through an n-channel gate-grounding transistor. The gate of this transistor is coupled by an ESD coupling capacitor to the output, ensuring that ESD pulses are effectively managed and do not damage the core transistors.
