ABSTRACT:
A buffer (200) having output devices (101 and 102) exhibiting complementary symmetry and configured as voltage-followers in push pull is biased for class AB operation by a bias network including two substantially equal resistors (201 and 202) arranged and configured to substantially reduce noise attributable to the bias circuit.
