This paper demonstrates experimentally how to reduce the nonlinearity of some analog and mixed-signal circuits by using the enhanced body effect provided by Fully-Depleted Silicon on Insulator (FD-SOI) CMOS technology. A current-starved CMOS inverter and a Voltage-Controlled Ring Oscillator (VCRO) are considered as case studies. The inverter is configured as a simple amplifier stage in which the harmonic distortion can be reduced and even removed by the combined action of the control voltages applied at the gate and bulk terminals of the current-source transistors. This current-starved inverter is used as the basic building block of a VCRO, where a more linear voltage-to-frequency characteristic can be achieved if the bulk terminal is used as the control voltage of the oscillator. The circuits under study have been designed and fabricated in a 28-nm FD-SOI technology and experimental results are shown to validate the presented approach. |
