A new family of low-voltage circuits based on quasi-floating gate transistors

A new family of very low-voltage analog circuits is introduced. These circuits do not show the GB degradation that characterizes other low-voltage approaches based on floating-gate transistors. The proposed approach is validated with experimental results of a CMOS mixer with 0.7 V input signal swing that operates on a single 0.8 V supply with transistor threshold voltages of 0.67 V.
