Delay lines, amplifier systems, transconductance compensating systems and methods of compensating |
摘要 |
Embodiments of delay lines may include a plurality of delay stages coupled to each other in series from a first stage to a last stage. Each delay stage may include an input transistor receiving a signal being delayed by the delay line. The delay line may include a compensating circuit configured to compensate for a change in a transconductance of the input transistor resulting from various factors. One such compensating circuit may be configured to provide a bias signal at an output node having a magnitude that is a function of a transconductance of a transistor in the compensating circuit. The bias signal may be used by each of the delay stages to maintain the gain of the respective delay stage substantially constant, such as a gain of substantially unity, despite changes in a transconductance of the respective input transistor in each of the delay stages. |
