With a total of 5 patents to his name, Ward's innovations have advanced the functionality and reliability of electronic devices.
Latest Patents
One of Ward's latest patents is the "Hysteretic Power-Up Circuit." This invention features a power-up circuit with hysteretic characteristics that regulate the activation of output buffers in extended logic circuits. The design allows for the switching transistor to turn on at a specific threshold voltage and remain active until a lower threshold is reached. This is achieved through two separate control paths that ensure stability despite fluctuations in power supply levels.
Another significant patent is the "BiCMOS Power-Up Circuit with Hysteresis." This circuit delays the operation of an extended circuit until the voltage is sufficiently high for all elements to function correctly. It is particularly useful for three-state output buffers connected to a common bus. The circuit maintains the output buffers in an inactive state until the power supply voltage is adequate, preventing unnecessary turn-offs caused by fluctuations.
