Abstract

A fully differential (FD) voltage buffer suited to low-voltage operation and able to operate over a wide voltage range is presented. The buffer core is based on a FD difference amplifier including bulk-driven MOS transistors as input devices. The common-mode (CM) component of the buffer output voltage is controlled by means of a bulk-driven CM feedback (CMFB) network that features an extended operating voltage range. The buffer was designed and fabricated in 0.35-μm CMOS technology for operation with a 1.5-V supply voltage. Experimental results illustrate the performance of the proposed solution.
