摘要:
A pseudo-differential switched-capacitor circuit using integrator-based common-mode stabilization technique is disclosed. A pseudo-differential switched-capacitor circuit with the differential floating sampling (DFS) technique has a common-mode gain value of one (1). An integrator is electrically coupled to the differential positive/negative outputs of the DFS circuit, and the integrator feeds back integrator output to the DFS circuit by detecting common-mode voltage disturbance at the differential positive output (Vout+) and negative output (Vout−), thereby stabilizing output common-mode level of the differential positive output (Vout+) and negative output (Vout−) at a desirable level.

公开了一种使用基于积分器的共模稳定技术的伪差分开关电容器电路。 具有差分浮动采样(DFS)技术的伪差分开关电容电路具有1(1)的共模增益值。 积分器电耦合到DFS电路的差分正/负输出,积分器通过检测差分正输出(Vout +)和负输出(Vout-)的共模电压干扰,将积分器输出反馈到DFS电路。 从而将差分正输出(Vout +)和负输出(Vout-)的输出共模电平稳定在理想水平。
