Bus Accelerator For Energy Reduction


I read your article Increase I2C or SMBus Data Rate and Reduce Power Consumption with Low Power Bus Accelerator, however I couldn't find any actual numbers on how much power is being saved using a bus accelerator. We are working on a wearable, which would have 4 devices on I2C bus, including a heart rate monitor and accelerometer, both of which will have ODR rate 100<, thus we were looking into using bus accelerator for energy reduction when reading the sensor data. Do you have any calculations / tests showing how much energy would actually be saved instead of using a pull-up resistors of e.g. 2.2 kOhms.
