Hello,
I am implementing a 10-bit sar adc using cadence. I have been stuck in the SA Register part. I am using 22 numbers of D-Flipflops. The single flip-flop circuit is functioning absolutely fine and all the 11 flip flips on the upper row in the below screenshot I have attached, are acting absolutely fine when the Q of one flip flop is connected to the D of the next flip flop. I am getting Q low and Qbar high in each flip flop of the upper row. Now when I am connecting the below flipflops and completing the register circuit, I am not getting the desired bit output, Can anyone please help me?
I am attaching the screenshots of the schematic and output pattern below.
