摘要：
Disclosed herein is a device that includes a bias line to which a bias current flows, a switch circuit controlling an amount of the bias current based on a control signal, a control line to which the control signal is supplied, and a cancellation circuit substantially cancelling a potential fluctuation of the bias line caused by changing the control signal, the potential fluctuation propagating via a parasitic capacitance between the control line and the bias line.
