AN2041 - Understanding PSoC® 1 Switched Capacitor Analog Blocks
Last Updated: 12/11/2012
AN2041 explains the operation of PSoC® 1's versatile switched capacitor analog blocks, and provides practical examples of their use.
Switched capacitor (SC) blocks are one of the two key components of PSoC 1's analog functionality, and can be reconfigured to perform many useful functions. Switched capacitor analog blocks are made up of a set of switched capacitors surrounding an opamp. The switched capacitors allow configuration of the block in many different modes, including as a comparator, amplifier, integrator, differentiator, ADC, and more. This application note explains the theory and application of these switched capacitor analog blocks.
