PHILLTM is a cutting-edge resonance actuation and tracking device, expertly designed for resonant sensors. It features a self-sustaining oscillator (SSO) and utilizes a frequency counter-based architecture, which is enhanced with wide band-pass and digital low-pass filtering. This advanced configuration optimally conditions signals by converting sinusoidal signals into precise rectangular waveforms. This initiation of the pulse generation mechanism effectively drives the resonator, ensuring accurate frequency data and robust stability without intermodulation noise.
Uniquely, PHILLTM offers the same frequency stability as systems using a Phase-Locked Loop (PLL) with a lock-in-based approach. However, it outshines traditional PLL systems by maintaining stability without ever losing 'lock'. This is due to its ability to freely select the oscillator bandwidth in the frequency counter, independent of circuit constraints. Additionally, PHILL simplifies operations by eliminating the need for PID parameter adjustments to track the resonator phase, offering a perfect blend of response speed and precision in performance.
