Title:
FILTER NETWORK
Document Type and Number:
Japanese Patent JPH01144717
Kind Code:
A
Abstract:
PURPOSE: To simplify constitution by providing a capacitor for switching the input of two other integrator circuits under the control of two disjoint clock states and mutually performing connection to the integrator circuit to linearize the phase/frequency response of a filter. CONSTITUTION: The two additional integrator circuits 36 and 38 are connected with each other and connected to the integrator circuits 12, 14 and 16 for the purpose of linearizing the phase/frequency response of a 2-port filter network 30. An additional structure body parallelly connected to the 2-port network 2 is equivalent to a passive constitution element acting to a phase for the purpose of linearizing the phase without disturbing the amplitude of the filter. Thus, the constitution is simplified.
