MOS capacitances used in mixed-signal circuits and their operative range [PDF]

open access: yesAdvances in Radio Science, 2003
To avoid additional layers for high linearity capacitances in modern CMOS process families, compensated depletion mode MOS capacitances can be used. As shown in previous publications, these MOS capacitances are suitable for low voltage applications.
