An envelope tracking supply modulator for a power amplifier is disclosed. The envelope tracking supply modulator comprises a multilevel push-pull converter. The multilevel push-pull converter comprises a control logic configured to generate a first and second control signals based on an envelope reference signal; a source multilevel converter configured to receive the first control signal and generate a source multilevel power supply signal; a sink multilevel converter configured to receive the second control signal and generate a sink multilevel power supply signal. The envelope tracking supply modulator further comprises a power recycling supply coupled to the sink multilevel converter; a low-pass filter coupled to outputs of the source and sink multilevel converters to filter the power supply signals generated from the source and sink multilevel converters.

The present invention discloses a method for identifying Wuzhishan miniature pig inbred line by using 145 SNPs. The method for auxiliarily identifying whether a pig to be tested is Wuzhishan miniature pig inbred line, provided by the present invention, comprises the following steps: testing genotypes based on 145 SNP sites of the pig to be tested; if all standards of (1) to (145) are satisfied, the pig to be tested is a candidate for Wuzhishan miniature pig inbred line; if all the standards of the above (1) to (145) are not satisfied, the pig to be tested is a candidate for non-Wuzhishan miniature pig inbred line.
