求高手翻译一句话，谢谢了啊啊收藏
The interface employs a 3rd-order feed-forwarddistributed-feedback SDM, which shares a single opampbetween its second and third integrator [14]. This reduces thepower consumption of the SDM.The force-feedback in the CMOS interface isimplemented by modulating the charge-pump’s outputvoltage. The charge-pump biases the sensor by charging thebackplate (BP) node, as shown in figure 3.. The chargepumpis implemented using four cascasded stages based onstatic charge-transfer-switches (CTS) [10]. The periodicboosting signals of the last stage, are adjusted in accordancewith the output of the SDM to modulate the bias voltage.The pre-amplifier of the interface bootstraps the parasiticcapacitances by tying its output to the substrate of the sensor,as shown in figure 3. This effectively removes Cp1 from thesignal path and also bootstraps Cp2. A bootstrapped Cp2offers much less loading to the charge-pump which has tomodulate the bias voltage with the SDM’s output. The dcbiasat the input of the ac-coupled pre-amplifier isestablished using pseudo-PMOS resistors [11].MEMS microphone, mainly because of its verticalstructure, is a single-ended electro-mechanical system. OtherMEMS sensors, such as accelerometers, facilitate theapplication of the force feedback due to their differentialstructure. This is because the feedback pulse applied to thesensor for force-balancing is cancelled as common-modenoise before reaching the readout interface. For the singleendedmicrophone sensor, the applied force feedback pulsegoes through the fixed bias capacitance (C0) between the twoelectrodes and reaches the output of the pre-amplifier.To convert the output of the pre-amplifier into a pseudodifferentialoutput, the interface uses a dummy branch with asimilar capacitive structure like the sensor. The dummystructure is bootstrapped just like the sensor and is also fedwith the force-feedback pulse. However, it is obvious that aperfect matching between MEMS capacitances andpoly/MIM capacitances in the dummy branch cannot beachieved. Consequently, the mismatch between the twobranches will translate into a variable offset at input of thedigital SDM. Figure 3 shows the scheme that is used in theinterface to minimize the mismatch between the twobranches[13].
