右腿驱动电路是一种在ECG系统中抑制电源及其他信号包括噪声共模干扰的方式，RLD电路测试被选电极的共模信号并通过反相共模信号驱动人体产生负反馈回路。负反馈回路根据回路增益降低共模增益。基于回路中不同的极点要针对用户系统具体使用稳定回路。因此，采用在电路上直接把RL(右下肢)和LL(左下肢)电路进行连接，这样在电路上就是一体的，向外引出的线缆也就相应减少一根，引出的线缆直接连接到LL(左下肢)，这样支导联就可以通过三个连接线来实现。The right leg drive circuit is a way to suppress power supply and other signals including noise common-mode interference in the ECG system. The RLD circuit tests the common-mode signal of the selected electrode and drives the human body to generate a negative feedback loop through the anti-phase common-mode signal. A negative feedback loop reduces the common-mode gain according to the loop gain. The stable loop is specific to the user system based on the different poles in the loop. Therefore, the RL (right lower extremity) and LL (left lower extremity) circuits are directly connected on the circuit, so that the circuit is integrated, and the outgoing cable is correspondingly reduced by one, and the outgoing cable is directly connected. to LL (left lower extremity), so that the branch lead can be realized by three connecting wires.

The central potential of Wilson is followed by the operational amplifier according to the three lead signals of RA, LA, and LL. The circuit is connected together through a 30k ohm resistor, and an 80pF capacitor is used for filtering. The central point voltage is input through the negative terminal of the operational amplifier.
