Using a quadrature XOR-gate (QXOR) reduces the second order harmonic term at the output, making it suitable to be used as a phase/frequency detector in high-frequency phase-locked loops. This paper introduces a 320 GHz PLL employing QXOR to cancel the reference spur, suppress in-band noise, and also...
