Switched-capacitor amplifier and applications
Abstract
A switched-capacitor (SC) amplifier in which the bias and load circuits are made of SC circuits is proposed. It is shown that by changing the control clock in the SC circuit, which is suitable for integration, the characteristics of the amplifier can be varied. An SC amplifier of the signal-recursion type is described. Since the SC amplifier is configured with only one active device and one set of peripheral components, it has a small size and a high gain. An example is given for an SC bandpass filter using the SC amplifier. It is concluded that the SC amplifier is useful for integration and low-power consumption of the SC network.
