Title:
SWITCH CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JP2016184918
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a switch control circuit that can implement an operation equivalent to supply of a proper DUTY ratio to even a circuit operating at a high frequency.SOLUTION: A switch control circuit includes a clock generation circuit 120 that generates one or more periodic signals having a predetermined period, a clock adjusting circuit 130 that adjusts a bias voltage for the periodic signal and changes an ON period of the one or more periodic signals to generate one or more control signals, and a switching circuit having one or more switches that are switched to ON when the amplitude of the at least one or more control signals is not less than a threshold value, and switched to OFF when the amplitude of the one or more control signals is less than the threshold value.SELECTED DRAWING: Figure 3
