A typical method for DCO fine-frequency tuning

The book presents an LC-based digitally controlled oscillator (DCO) using a capacitive degeneration technique with an enhanced frequency resolution and an extended linear frequency tuning range. Contents: 1) An L, S and S2 bands, compliant LC-based DCO for Amateur Nano-Satellite Applications. 2) A fine frequency tuning for LC-DCO using enhanced capacitive degeneration technique. 3) A 5-mW, 1.2-3.5-GHz Capacitive Degeneration in LC-Digitally Controlled Oscillator for Nano-Satellite Frequency Synthesizers in 90-nm CMOS.
