CHRT Design

On Botoks, the CHRT is implemented with off the shelf SMD components. To support a wide variety of applications the following requirements are set for the CHRT. These requirements are listed in [time-able range, resolution].

Requirements = [
  [0.1,0.001]
  , [1,0.01]
  , [10,0.1]
  , [100,1]
  ]

By entering these requirements in chrt.py found in the scripts folder and executing the script, these requirements are translated into a CHRT configuration.

$ python chrt.py

Resulting in a configuration of 4 tiers with 2.2nF, 22nF, 220nF and 2.2uF capacitors, as present on the Botoks sensor.

The scripts operates by iterating over different capacitor sizes to find a suggested CHRT configuration for the requirements.
