적분기의 전달 특성은 기생 용량으로 인한 과잉 위상 변이의 영향을 받습니다. 위상 보상은 위상 리드를 생성하기 위해 0.5을 도입하여 얻습니다. 본 논문에서는 차동 신호 입력 적분기의 위상 보상 기법을 제안한다. 제안된 기법은 피드포워드 신호 전류원을 사용한다. XNUMXdB 통과대역 리플을 갖는 XNUMX차 도약 체비쇼프 저역통과 필터는 제안된 위상 보상을 갖춘 적분기를 사용하여 설계되었습니다. 또한, PLL 시스템을 적용하여 제안 기법을 이용한 자동튜닝 위상보상 시스템을 구현한다. 제안된 기법의 유효성은 PSPICE 시뮬레이션을 통해 확인되었다. 제안된 위상 보상을 적용한 적분기의 시뮬레이션 결과는 다양한 단위 이득 주파수에서 초과 위상 제거가 얻어지는 것을 보여줍니다. XNUMX차 도약 필터의 정확한 필터 특성은 자동 튜닝 위상 보상 시스템을 사용하여 얻습니다. 필터의 통과대역은 넓은 주파수 범위에서 향상됩니다. 제안된 기법은 저전압 애플리케이션에 적합하다.

Abstract: The transfer characteristic of an integrator is affected by excess-phase shift caused by the parasitic capacitance. The phase compensation is obtained by introducing zeros to generate phase lead. This paper proposes a phase compensation technique for the differential signal input integrator. The proposed technique is employing feedforward signal current source. The fifth-order leapfrog Chebyshev low-pass filter with 0.5 dB passband ripple is designed using the integrator with the proposed phase compensation. Further, an autotuning phase compensation system using the proposed technique is realized by applying a PLL system. The effectiveness of the proposed technique is confirmed by PSPICE simulation. The simulation results of the integrator with the proposed phase compensation shows that excess-phase cancellation is obtained at various unity gain frequencies. The accurate filter characteristic of the fifth-order leapfrog filter is obtained by using the autotuning phase compensation system. The passband of the filter is improved over wide range of frequencies. The proposed technique is suitable for low voltage application.
