Abstract
An amplifier includes an inverter with two transistors of complementary types. The first transistor is biased through a third transistor of the same type of conductivity by a first reference voltage, the third transistor being biased by a third voltage of reference. The second transistor is biased through a fourth transistor of the same type of conductivity by a second voltage of reference, the fourth transistor being biased by a fourth voltage of reference. The first and second voltages of reference are determined so that without any alternating input signal the current in the first and second transistors of the inverter is minimum. The third and fourth voltages of reference are determined so that the equivalent resistances of the third and fourth transistors are very high.
