Introduction

Danielle L Coffing is a prominent inventor based in Tempe, AZ (US). She has made significant contributions to the field of electronics, holding a total of 8 patents. Her work primarily focuses on circuits and methods that enhance signal processing and frequency control.

Latest Patents

One of her latest patents is titled "Circuit and method for processing an automatic frequency control signal." This invention involves an integrated demodulator tuning circuit that receives differential currents at input terminals and provides an AFC signal at an output terminal. The AFC current characteristic features a dead band in the output current generated when the circuit operates under specific conditions. The set threshold value is determined by the relative sizes of the transistors that form the current mirrors connected to the input terminals.

Another notable patent is "Demodulator and method for second harmonic cancellation." This demodulator circuit receives an input signal and generates an oscillator signal in an oscillator circuit. The oscillator signal is locked to the same frequency and phase as the input signal. A phase shift circuit generates a shifted signal that is in quadrature with the oscillator signal. The output signals generated by the multipliers are summed in a summing circuit to provide the final output signal.
