Title: **Innovations of Benjamin J. McCarroll: Pioneering Advances in Electronic Devices**
Introduction
Benjamin J. McCarroll, an accomplished inventor based in Portland, OR, has made significant contributions to the field of electronics with a portfolio of nine patents. His work primarily focuses on advancing technologies related to light-emitting diodes (LEDs) and digital-to-analog converters (DACs).
Latest Patents
One of McCarroll's notable latest inventions revolves around **matched filter techniques configured to fire LEDs using a sloped response**. This invention describes an electronic device that employs a matched filter to drive an LED module. The matched filter effectively processes incoming rectangular pulses to produce a modulated driving signal that powers the LED. The optical output from the LED is captured by an optical sensor, which converts it into an electrical signal for further analysis. To enhance the device's performance, a decimation filter is integrated to reduce the sampling rate and minimize quantization noise, facilitating an optimal signal-to-noise ratio (SNR) at a fixed power level.
Another remarkable patent by McCarroll is focused on **data encryption for suppression of data-related in-band harmonics in digital-to-analog converters**. This invention addresses the challenge of input data harmonic leakage through parasitic capacitance in IC packages. It details a method of off-chip input data encryption, utilizing an exclusive-OR operation between raw data and a random bit stream. Upon reaching the DAC chip, the data undergoes on-chip decryption using identical circuitry and the same random bit stream. By encrypting the input data, McCarroll’s invention significantly reduces harmful harmonic content, thereby maintaining DAC narrow-band linearity with minimal impact on spectral noise.
