Dalam makalah ini kami memperkenalkan pengayun terkawal voltan (VCO) voltan rendah/kuasa rendah (LV/LP) CMOS. Ia termasuk penukar VI mudah, pengayun cincin terkawal semasa berdasarkan sel kelewatan pembezaan baharu, dan pasangan pembezaan berganding sumber untuk menukar isyarat pembezaan kepada isyarat hujung tunggal. Penukar VI dilaksanakan sebagai jenis pengikut sumber, mempamerkan lineariti transkonduktans yang sangat baik dengan penggunaan kuasa yang rendah. Sel tunda baharu menggunakan maklum balas positif tempatan untuk meningkatkan keuntungan DCnya, mencapai ayunan yang stabil pada voltan bekalan rendah. Hasil simulasi dan pengukuran diberikan untuk menunjukkan kelinearan antara input (voltan kawalan) dan output (frekuensi) dalam julat frekuensi 100 MHz hingga 400 MHz dengan bekalan kuasa 1. 2 V. VCO hanya menggunakan kuasa 2.25 mW pada frekuensi operasi 400 MHz dan bekalan 1.2 V.

Abstract: In this paper we introduce a CMOS low voltage/low power (LV/LP) voltage controlled oscillator (VCO). It includes a simple V-I converter, a current controlled ring oscillator based on new differential delay cells, and a source-coupled differential pair to convert differential signal to single-ended signal. The V-I converter is implemented as a source follower type, exhibiting excellent linearity of transconductance with low power consumption. The new delay cell employs local positive feedback to increase its DC gain, achieving stable oscillation at low supply voltage. The simulation and measurement results are given to show the linearity between the input (control voltage) and the output (frequency) in the frequency range of 100 MHz to 400 MHz with 1. 2 V power supply. The VCO only consumes power of 2.25 mW at operating frequency of 400 MHz and 1.2 V supply.
