Abstract :
We present implementations of highly linear amplifier and multiplier circuits that employ a linear CMOS resistor. This tunable resistor is built by utilizing the common-mode linearization technique, and by exploiting the gate-coupling and charge-storage characteristics of the floating-gate transistors. It exhibits 0.01% THD for 1Vpp input. Also, the amplifier has an input linear range of 2.5Vpp for differential and single-ended inputs, and achieves 0.018% THD for 1Vpp differential input
