Abstract
A circuit comprises an analog output module that receives a bias signal and a control signal. A delay module receives a first signal and that generates a delayed first signal. A control module receives the delayed first signal and generates the control signal based thereon. An envelope generating module receives a second signal including amplitude information related to the first signal and generates an envelope signal that selectively increases the bias signal to the analog output module when the envelope signal exceeds a predetermined threshold and before a corresponding portion of the first signal is received by the analog output module.
Claims29
A circuit comprising:
- an analog output module that receives a bias signal and a control signal;
- a delay module that receives a first signal and that generates a delayed first signal;
- a control module that receives the delayed first signal and that generates said control signal based thereon;
- and
- an envelope generating module that receives a second signal including amplitude information related to said first signal and that generates an envelope signal that selectively increases said bias signal to said analog output module when said envelope signal exceeds a predetermined threshold and before a corresponding portion of said first signal is received by said analog output module.
A circuit comprising:
- analog output means for receiving a bias signal and a control signal;
- delay means for receiving a first signal and for generating a delayed first signal;
- control means for receiving the delayed first signal and for generating said control signal based thereon;
- and
- envelope generating means for receiving a second signal including amplitude information related to said first signal and for generating an envelope signal that selectively increases said bias signal to said analog output means when said envelope signal exceeds a predetermined threshold and before a corresponding portion of said first signal is received by said analog output means.
A method comprising:
- receiving a bias signal and a control signal at an analog output module;
- receiving and delaying a first signal;
- generating said control signal based on the delayed first signal;
- receiving a second signal including amplitude information related to said first signal;
- and
- generating an envelope signal based on said second signal that selectively increases said bias signal to said analog output module when said envelope signal exceeds a predetermined threshold and before a corresponding portion of said first signal is received by said analog output module.
