He has made significant contributions to the field of technology, particularly in the area of signal processing and frequency synthesis. With a total of three patents to his name, Shields has demonstrated his expertise and innovative spirit in developing advanced devices and methods.

Latest Patents

One of Shields' latest patents is for a "Direct conversion receiver device with first and second stages and related methods." This device is designed to receive I and Q signals and includes a blind IQ balance circuit that balances these signals without the need for a pilot signal. The mixer coupled to this circuit generates I and Q baseband signals based on the operational frequency, which is determined by the bandwidth and modulation of the I and Q signals. The blind IQ balance circuit features a first stage that produces an intermediate amplitude balanced Q signal and a second stage that generates phased balanced I and Q signals.

Another significant patent by Shields is the "Direct digital synthesis (DDS) phase locked loop (PLL) frequency synthesizer and associated methods." This synthesizer incorporates a phase detector that receives a reference signal and a controlled oscillator that generates a synthesized frequency output signal. The design allows for narrow frequency steps, achieving fine frequency tuning resolution while minimizing output spurs and maintaining low phase noise.
