    SC Block Basics

      Description of PSoC 1 is incomplete without the mention of switched capacitor blocks. It is this feature, which makes the device unique. Switched capacitor blocks are highly configurable hardware blocks which can be configured to work as an amplifier, comparator, modulator, filter, ADC, DAC, integrator, differentiator and so on. And the story doesn't end here; you can even tune parameter of the function during run time. For example, changing the gain of amplifier, changing threshold in comparator, adjusting cut off frequency in filter, changing the integration time constant etc.

         

      Here are some collaterals associated with switched capacitor blocks:

      Last but not the least...Technical reference manuals are the ultimate resource to understand any feature of PSoC 1 device in great amount of detail.
