This paper presents a LC-based digitally controlled oscillator (DCO) with an enhanced frequency resolution and an extended linear frequency tuning range. It generates frequencies between 1.22 and 3.52 GHz that covers three main bands defined for amateur Nano-satellite applications (L, S and S2). The DCO exploits a new tunable active inductor (TAI) that achieves a high Q-factor with a maximum value of 98 over a frequency range of 1770 MHz. It tunes from 3.55 nH to 15.2 nH. Furthermore, a tuning circuitry based on a capacitive degeneration network formed by a capacitance with an additional resistance, is employed to achieve a low frequency resolution without any dithering. The achieved frequency resolution is approximately between 3 and 16 kHz. The DCO exhibits a phase noise of −105.8 dBc/Hz at 1MHz frequency offset and an FoM of −175 dBc/Hz. Finally, the circuit consumes 5.2 mA current when is designed in a 90-nm nine-metal CMOS technology with an operating supply voltage of 1.0 V. |
