Digital automatic gain control for transceiver devices |
摘要 |
An automatic gain controller for transceiver elements uses a digital topology to achieve an efficient and rapid gain settling so that an output signal of the variable gain section is within a predefined range. In one embodiment, an input signal is periodically sampled and latched so as represent the gain excess of a variable gain section. An accumulator, including an adder having saturation characteristics and a latch as a feedback element, creates a number for a new gain setting so that the variable gain section may adapt to the new gain setting within one clock period. In one example, a gain range of 84 dB is controllable and settling is achieved within 3 clock periods at most.
