Latest Patents

Among his latest patents is an electronic device that utilizes a first voltage and a second voltage, which is lower than the first. This device features an internal circuit that operates on the second voltage and produces an output signal corresponding to it. Additionally, it includes an interface circuit that receives the output signal and shifts it to a level corresponding to the first voltage, providing the shifted output signal to a pad. Notably, the interface circuit is equipped with an electrostatic discharge (ESD) block connected to the pad and comprises multiple transistors that are driven at the second voltage and fail at the first voltage.

Another significant patent involves an electronic system that includes an input/output circuit. This circuit features a pull-up driving circuit with at least one internal node linked to a pad, designed to elevate the pad's voltage to a Tx power supply voltage. It also includes a pull-down driving circuit that lowers the pad's voltage to ground. The pull-up driving circuit is engineered to set the internal node's voltage level based on a fixed voltage when the voltage difference between the Tx power supply voltage and the pad's voltage exceeds the power supply voltage level.
