Title: John Memishian: Innovator in Analog Technology
Introduction
John Memishian is a prominent inventor based in Weston, MA (US). He has made significant contributions to the field of analog technology, holding a total of 8 patents. His work focuses on developing advanced systems and methods that enhance the performance and efficiency of electronic devices.
Latest Patents
One of his latest patents is for a high-resolution analog to digital converter (ADC). The systems, methods, and devices disclosed in this patent relate to a bit-per-stage ADC that extracts one or more bits at each stage and creates a residue. This allows succeeding similar or identical stages to extract more bits. The ADC utilizes a reflected binary output code, enabling bit extraction by observing the sign of an input. The residue generation involves rectifying the input, multiplying it by two, and level-shifting it by half the span, all achieved using capacitors and switches. This innovative approach results in low power consumption and a compact size.
Another notable patent focuses on activity detection in MEMS accelerometers. This method involves storing a value of acceleration, measuring acceleration at a later time, and calculating a change in acceleration. The change is then compared to an activity threshold to detect activity. A similar technique is used to detect inactivity, where the change in acceleration is compared to an inactivity threshold. If the change is less than the threshold and a predetermined period has elapsed, inactivity is detected.
