Linear CMOS trans-conductors are versatile analog building block that find wide, but not exclusive, use in the implementation of continuous-time filters, data converters, fuzzy controllers or V-I converters for interfacing with current mode signal processing circuit. Often in these applications the input trans-conductor determines the overall linearity of the system. Modern fabrication technologies and wireless applications also require low supply voltage and low power consumption, which make it difficult to achieve trans-conductors with high linearity and low supply voltage over a reasonable input range.
