An efficient clocked class AB fully differential rail to rail differential difference amplifier is introduced. It is based on a two stage operational amplifier architecture with resistive local common mode feedback, floating gate transistors in the input stages and in the common mode feedback network. Its application in fully differential rail to rail high performance sample and hold circuits is discussed. Other applications discussed include fully differential buffers and single ended to fully differential converters with enable input. Experimental results of a test chip prototype fabricated in 0.5μm CMOS technology validate the proposed scheme. The fabricated track and hold has an SFDR=69.5dB with a clock frequency of 2MHz and 2Vpp, 200KHz input signals. |
