Latest Patents

One of Twigg's latest patents is titled "Systems and methods of providing programmable voltage and current reference devices." This invention describes systems and methods for providing stable and programmable voltage and current reference devices. An exemplary embodiment of this invention provides a voltage reference device that includes a first floating-gate transistor with a first source, a first drain, and a first gate. The first gate is coupled to a first programming capacitor and a first input capacitor. Additionally, the voltage reference device includes a second floating-gate transistor with a second source, a second drain, and a second gate, which is coupled to a second programming capacitor and a second input capacitor. The charge difference between the two floating-gate transistors serves as a reference voltage.

Another notable patent is "Systems and methods for programming large-scale field-programmable analog arrays." This invention presents a large-scale field-programmable analog array (FPAA) designed for rapidly prototyping analog systems and generating arbitrary analog waveforms. The FPAA includes a floating-gate transistor array and multiple computational analog blocks (CABs). These CABs can be adapted to set bias voltages for operational transconductance amplifiers (OTAs), adjust corner frequencies on capacitively coupled current conveyors, and set multiplier coefficients in vector-matrix multipliers. The floating-gate transistors can function as switch elements, programmable resistor elements, precision current sources, and programmable transistors, allowing for on-chip programming of the characteristics of the computational elements.
