Engineering Report Featuring a Comparison of the Qualcomm MSM6280 and MSM7200

The engineering report is the full circuit extraction of the Qualcomm MSM6280 Analog die minus the SBI block and associated circuitry. This report makes a comparison between the Qualcomm MSM6280 and MSM7200.

This engineering report has all the schematics sizing and hierarchy done. There is limited to no analysis done which would be the only thing needed to turn this report into a Key Feature Report.






This engineering report features the following sections:

· Device Summary Table
· Introduction
· Architectural Overview
· Schematics of the complete analog die, including the ADC's and DAC's which includes the following:

· GSM/UMTS receive ADC with an additional BiQuad filter

· GPS receive ADC

· Tx DAC, TX output amplifiers with filters

· 2nd Tx DAC with output amplifiers and filters.

· Sigma Delta ADC which is most likely used to close the loop for the transmit DAC's.

· Bias generation circuitry.
