Figure Lengend Snippet: ( a ) Post layout simulation of ADC together with AFE and I2C when the capacitive MEMS pressure sensor (Cx) = 6 pF. The C-V output voltage is 0.59 V and the ADC digital decimal output is 299. ( b ) Zoom of AFE output, Vi (Integrator output), and SDA_M from 20.73 to 20.81 ms in ( a ). The simulated rms total current consumption is 180 uA.
