摘要：

The use of the bulk terminal to enhance the linear properties of the MOS transistor is examined. Firstly, bulk-linearization of a MOS differential pair is presented, including harmonic distortion measurements. Then bulk-degeneration technique is extended to the triode region to implement large MOS pseudo-resistors. A new asymmetric bulk-modified composite MOS with an equivalent saturation voltage of several hundred mV is introduced, and a 150M Omega pseudo-resistor by stacking a few of these stages is presented. Finally, bulk-linearization of the MOS differential pair and the MOS resistor are combined to implement a 6.4nS transconductor with above 1V linear range, consuming only 6nA, improving the compromise between linear range and power consumption of previously reported small transconductance OTAs.
