Latest Patents

Among his latest patents is the "Integrated Defibrillation Pulse Protector," which discloses a Silicon-controlled rectifier (SCR) based circuit designed for ECG protection under defibrillator pulses. This SCR-based clamp features a symmetric structure that provides dual-direction voltage tolerance protection. It is based on two anti-series P-well/N-well lateral blocking junctions that are isolated from the P-substrate by an N-buried layer. The injector regions (n+/p+) are lengthened to accommodate a larger number of contact rows than typically used for ESD pulse specifications. Additionally, a stack of metal layers can be utilized to provide high current and heat-sink capability, with each electrode metal layer fully filled with VIAs.

Another significant patent is the "Input Voltage Clamp for a Single-Supply System." This invention describes a system, apparatus, and method that provide a voltage clamp for a single-supply system. Specifically, it includes a negative voltage clamp that prevents negative over-voltage in systems with only a positive independent voltage source. This is particularly useful for certain analog-to-digital converters and other circuits that allow input signals below the negative supply or ground in single-supply systems. The negative clamp ensures accurate negative over-voltage protection, addressing a critical need in electronic circuit design.
