Gm-C is open loop structure, therefore it can be relatively fast and low power. But the linearity and dynamic range is lower, because of its open loop.
OTA-C has better linearity, but more power consumption.
SW-C does not require tuning, but need faster OTA, therefore more power. Clock noise need to be carefully considered in a system. |
