Latest Patents

One of his latest patents is titled "Means of integrating a microphone in a standard integrated circuit process." This invention discloses a method for integrating a microphone on the same integrated circuit die as other electronics. The structure utilizes solder bump technology to create a gap between an electrode on the silicon and another electrode. This design allows for area efficiency by enabling the placement of active silicon circuitry beneath the microphone. The microphone's operation is based on changes in capacitance caused by sound wave pressure, which alters the charge stored on the capacitor.

Another significant patent is the "Low noise resistorless band gap reference." This invention is designed to provide a band gap voltage reference with the necessary temperature coefficient without amplification. It achieves this through the careful selection of junctions and current densities, requiring only one polarity of bipolar transistors. The design results in a lower noise reference compared to other designs, as the noise terms of each junction add in root mean square rather than through linear amplification.
