Pengayun terkawal voltan (VCO) bertolak ansur untuk memproses variasi pada voltan bekalan yang lebih rendah telah dicadangkan. Litar ini terdiri daripada litar pemantauan ambang-voltan pada cip, litar sumber arus, litar kawalan pincang badan dan sel tunda VCO. Oleh kerana variasi dalam kekerapan VCO voltan rendah ditentukan terutamanya oleh arus dalam sel tunda, teknik pampasan arus telah diguna pakai dengan menggunakan litar pemantauan ambang-voltan pada cip dan teknik litar pincang badan. Simulasi SPICE Monte Carlo menunjukkan bahawa variasi dalam kekerapan ayunan dengan menggunakan teknik yang dicadangkan dapat ditekan kira-kira 65% pada voltan bekalan 1-V, berbanding dengan frekuensi dengan dan tanpa teknik.

Abstract: A voltage-controlled oscillator (VCO) tolerant to process variations at lower supply voltage was proposed. The circuit consists of an on-chip threshold-voltage-monitoring circuit, a current-source circuit, a body- biasing control circuit, and the delay cells of the VCO. Because variations in low-voltage VCO frequency are mainly determined by that of the current in delay cells, a current-compensation technique was adopted by using an on-chip threshold-voltage-monitoring circuit and body-biasing circuit techniques. Monte Carlo SPICE simulations demonstrated that variations in the oscillation frequency by using the proposed techniques were able to be suppressed about 65% at a 1-V supply voltage, compared to frequencies with and without the techniques.
