Latest Patents
One of Matthews' latest patents is a method and circuit for maintaining I/O pad characteristics across different I/O supply voltages. This invention implements a circuit that adjusts the I/O characteristics of an I/O pad circuit based on the value of the I/O supply voltage. The circuit detects the supply voltage relative to a known reference and selectively enables portions of the I/O pad circuit in response. By controlling the ratio of P-channel and N-channel transistors, the physical characteristics of the circuit, such as slew rate and signal rise and fall times, can be optimized for various applications.
Another significant patent is an output buffer circuit and method of operation. This output buffer contains low, medium, and high voltage drivers. The innovative two-stage low-to-high driving methodology minimizes delay time from input to output. The design includes protection transistors that facilitate error-free programming during reset operations.
