Latest Patents

Hayes' latest patents include a pre-amplification conditioning circuit for a transducer audio device. This innovative microphone system features a pre-amplification conditioning circuit housed within a compact design. It comprises a pair of matched JFETs configured in a differential pair with a common-source configuration. When biased, these JFETs are operable to receive and amplify the differential microphone output signal. Additionally, the system includes a pair of BJTs configured as a complimentary feedback transistor pair, enhancing the overall performance. The design also incorporates a current sink that maintains a fixed total direct current through each of the matched JFETs and BJTs. This configuration reduces the corresponding electrical load on the JFETs, minimizes signal noise, and increases the maximum amplified microphone output signal level.
