He has made significant contributions to the field of frequency synthesis, holding 2 patents that showcase his innovative approach to technology. His work has been instrumental in advancing the capabilities of frequency synthesizers.

Latest Patents

Barnett's latest patents include a "Synchronized frequency synthesizer with high speed lock." This invention utilizes a first order loop and sample-and-hold phase detector with optimized gain to achieve very fast frequency locking characteristics. Additionally, it incorporates synchronization of the programming of the loop divider and the range shifting of the voltage-controlled oscillator. An adaptive loop filter is also provided, allowing a first order loop to be used for lock acquisition while maintaining excellent noise performance after the lock has been obtained.

Another significant patent is the "Divider with dual modulus prescaler for phase locked loop frequency." This high-frequency divider is suitable for use in a frequency synthesizer, employing a dual modulus prescaler and two counters to achieve high speed and low current drain. The input signal is alternately divided by one of the two moduli in the prescaler and then alternately divided by one of the two counters. Each counter is reset while the other is counting, thereby reducing circuit complexity and increasing circuit speed.
