Abstract
A new class of configurations for linear low-voltage/low-power transco nductors is presented. With a single supply voltage of 1.0V, a dynamic range of > 100dB within the audio bandwidth is feasible. The linearit y exceeds 99% within an input voltage between -9 and +9 times the ther mal voltage. Owing to class-AB operation the quiescent power consumpti on is extremely low. A special biasing technique, called 'indirect bia sing' ensures stable biasing and large PSSR.
