ABSTRACT:
A wavelet transform noise minimization circuit comprises a differential receiver, a voltage comparator, a wavelet transform circuit, an electrical idle (EI) detector circuit, a phase interpolator, a phase-locked-loop (PLL), and a reference clock buffer. The wavelet transform noise minimization circuit may be beneficially applied wherever there is non-deterministic (e.g., random) noise in the PHY layer during an electrical idle state. The wavelet transform noise minimization circuit may be used to improve noise margin during an electrical idle state, and/or reduce the occurrence of false activation of a PHY layer when in the electrical idle state.
