Continuous time common-mode feedback module and method with wide swing and good linearity |
摘要 |
A continuous time common mode feedback module is capable of operating in a wide range of input voltages. The common mode feedback module includes a common mode detector and an amplifier for computing and amplifying the difference of a reference voltage and a common mode voltage of a first input signal and a second input signal. The common-mode feedback module includes a common mode resolver and a control voltage generating module coupled to each other to provide a common mode feedback voltage. The common mode feedback module provides a good linearity and a wide bandwidth, without compensation requirements. The common mode feedback module also provides small process corner dependence of bias current and a common mode offset.
