“…Another useful technique is gm boosting, which can be achieved in two ways: (1) the current paths can be arranged at the gates of two cross-coupled MOSFETs [27], [28], [29], [30], [31], [32], [33], [41], [42] or (2) the current paths can be arranged in parallel with two other MOSFETs [8], [9], [36], [43]. These methods increase the oscillation amplitude of the output signal and support rapid start-up.…”
