Apparatus and methods for programmable slew rate control in transmitter circuits |
摘要 |
High speed transmitter drivers and other types of driver circuitry may be required to produce output signals with variable slew rates. Driver circuitry and methods for providing variable slew rate control are described. Pre-driver circuitry with variable slew-rate may be used to supply signals with variable slew rate at the driver input. The driver and/or pre-driver circuits may include transistors with variable drive strengths. The driver and/or pre-driver circuits may also include selectably enabled stages for varying the circuit drive strength. The pre-driver circuitry may be delay matched to maintain signal quality. Other circuitry and methods are also described.
