Abstract:
1. A method for receiver optimization in a receiver with bypassable decimation filters, comprising: injecting a signal into an input of the receiver; enabling a bypass select enable for the decimation filters such that the signal bypasses the decimation filters; optimizing a programmable gain amplifier; and disabling the bypass select enable for the decimation filters, wherein the step of optimizing the programmable gain amplifier further comprises: A. selecting a sampling phase out of a set of sampling phases; B. configuring sampling phase selects for a downsampling circuit corresponding to the selected sampling phase; C. downsampling the signal, producing a downsampled signal; D. measuring signal power of the downsampled signal; E. repeating the steps A–D for remaining sampling phases; F. combining measured signal powers of downsampled signals, producing a measured signal power of the signal; and G. adjusting gain of the programmable gain amplifier according to the measured signal power of the signal.
