| 摘要 | A transconductance adjustment circuit includes a reference signal generation circuit that outputs a first signal and a second signal that is different by 90 degrees in phase from the first signal, a replica circuit to which the first signal and the second signal are input and which generates a first output signal and a second output signal, and an adjustment signal generation circuit that outputs a transconductance adjustment signal with respect to the adjustment-targeted circuit and the replica circuit. The reference signal generation circuit generates the first signal and the second signal that change in voltage at between a first voltage level and a second voltage level, based on a clock signal, and outputs the generated first and second signals with respect to the replica circuit. | ||

| 主权项 | 1. A transconductance adjustment circuit comprising: a reference signal generation circuit that outputs a first signal and a second signal that is different by 90 degrees in phase from the first signal; a replica circuit receiving the first signal and the second signal from the reference signal generation circuit as input and which generates a first output signal and a second output signal that are shaped as sinusoidal waves, wherein the first signal and the second signal are shaped as square waves; and an adjustment signal generation circuit that receives the first output signal from the replica circuit and the second signal from the reference signal generation circuit and outputs a transconductance adjustment signal to an adjustment-targeted circuit and the replica circuit, wherein the adjustment-targeted circuit is external to the transconductance adjustment circuit, wherein the reference signal generation circuit generates the first signal and the second signal that change in voltage at between a first voltage level and a second voltage level, based on a clock signal, and outputs the generated first signal and second signal to the replica circuit. | ||
