摘要：
Different from conventional two-point modulation (TPM) type-II PLLs requiring non-trivial gain calibrations and TPM type-III PLLs with loop stability concern and limited chirp rate, a self-adapting gain-mismatch TPM type-II digital PLL is proposed. The measurement results indicate that the proposed PLL can generate a precise triangular chirp with 2.27 GHz BW and 18.2 μs period, which demonstrates the widest normalized chirp bandwidth and the fastest chirp rate simultaneously.
