Abstract:
Apparatus and associated methods relating to the amplification of an audio signal. In particular, such application is performed by using an audio to pulse train converter configured to convert an analog audio signal to a complementary train of pulses having a duty cycle indicative of the level of the analog audio signal. The audio to pulse train converter can be a class-D amplifier, a sigma-delta amplifier, self-oscillating amplifier, or any other audio amplifier that is configured to provide complementary pulse trains each having a duty cycle that is representative of the input audio signal. The complementary pulse trains are directed to a circlotron that is configured to provide an amplified version of the audio signal at two output nodes. The amplifier circuit may further include one or more low pass filters and/or output reference resistors. Two similar circuits can be configured together to provide stereo audio amplification.

Claim (Index 1):
A system for producing amplification of an analog audio signal, the system comprising:\n an analog to pulse train converter configured to convert the analog audio signal to a complementary train of pulses indicative of the analog audio signal, the analog to pulse train converter receiving the analog audio signal at an input port and providing the complementary train of pulses at an output port; and a circlotron having two active devices, two power supplies, two complementary input terminals, and two complementary output nodes, wherein each of the active devices has a control node in conductive communication with a respective one of the complementary input terminals, wherein the complementary input terminals are configured to receive the complementary train of pulses; wherein the circlotron is configured to amplify the complementary train of pulses, thereby producing an amplified version of the analog audio signal at the two output nodes.
