1. Wang Jia reported some test analysis of the LDO blocks in Tcpx2 chip. One suspicious problem is that the antenna diode in the WB region might have weak connection problem, and then make the signal wire unwantedly soft-connect to the power supply. We later found similar suspicious points in the DAC design. We need to first make sure about this problem, and then find a solution for the antenna effect.
2. Some designs for the engineering run have been collected. We will try to finish the design as scheduled at the beginning of April.
3. The bidding issue for the engineering run should be pushed forward, so as to make the design be submitted in time.
