Abstract:
1. A transmitter module with an active linear amplifier circuit, comprising: a header electrically coupled to a chassis ground; a first input node configured to receive a first data signal; a second input node configured to receive a second data signal that is complementary of the first data signal; a buffer stage having a first node coupled to the first input node and a second node coupled to the second input node; an amplifier stage having a fifth node coupled to a third node of the buffer stage and having a sixth node configured to be coupled to a signal ground, wherein the signal ground is not coupled to the chassis ground; an optical transmitter having an eighth node coupled to a seventh node of the amplifier stage and having a ninth node configured to be coupled to a voltage source; a bias circuit configured to couple a fourth node of the buffer stage to a bias current source; and a thermal chirp compensation circuit having an eleventh node coupled to a tenth node of the buffer stage and having a twelfth node coupled to the bias circuit.
