Patent number: 9054644Abstract: Systems and methods are provided for amplifying multiple input signals to generate multiple output signals. An example system includes a first channel, a second channel, and a third channel. The first channel is configured to receive one or more first input signals, process information associated with the one or more first input signals and a first ramp signal, and generate one or more first output signals. The second channel is configured to receive one or more second input signals, process information associated with the one or more second input signals and a second ramp signal, and generate one or more second output signals. The first ramp signal corresponds to a first phase. The second ramp signal corresponds to a second phase. The first phase and the second phase are different.Type: GrantFiled: August 29, 2013Date of Patent: June 9, 2015Assignee: On-Bright Electronics (Shanghai) Co., Ltd.Inventors: Tingzhi Yuan, Yaozhang Chen, Lieyi Fang
