Gm-C & Switch-Cap Filter

[Willt]

Hi friends,

Are there any recommended GOOD books for the introduction of Gm-C filter and Switch-Cap filter? I know a little bit about them. It seems to me that Gm-C filter is easier to design and understand.

Gm-C filter ~ adv. high frequency, disadv. inaccurate, non-linear

Switch-Cap filter ~ adv. accurate, linear, disadv. relatively low frequency, require clock signals

Thanks a lot ~
