Patent ID: 6995611

Claim:
An inductive amplifier, comprising: a first stage coupled to receive an input signal and adapted to draw an output current from intermediate output nodes in response to the input signal, the first stage including a first differential transistor pair having common first conductors coupled to a first node and having second and third conductors coupled to the intermediate output nodes; and a first current source coupled to the first node and adapted to conduct the output current drawn from the first and second intermediate output nodes; and a boost stage coupled to the intermediate output nodes and coupled to receive the input signal, the boost stage including a second differential transistor pair having common first conductors coupled to a second node and having second and third conductors coupled to the intermediate output nodes; and a second current source coupled to the second node and adapted to conduct the variable current drawn from the intermediate output nodes, wherein the boost stage is adapted to draw a variable current from the intermediate output nodes in response to a frequency of the input signal to modify a magnitude of the output current drawn.
