Patent number: 9013234Abstract: 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.Type: GrantFiled: April 9, 2013Date of Patent: April 21, 2015Assignee: Seiko Epson CorporationInventor: Toshiyuki Misawa
