Aspects of this disclosure relate to adjusting a phase of a clock signal provided to a device based on a feedback signal from the device. The feedback signal can provide phase information associated with the device and/or other information associated with the device, such as temperature information. A feedback signal processor can compute a phase control signal based on the feedback signal. The phase control signal can be used to adjust the phase of the clock signal. By adjusting the phase of one or more clock signals, several devices, such as data converters, can be synchronized.

A multi-channel clock distribution circuit and an electronic device includes a power source, a first switch, and at least two clock distribution sub-circuits; each clock distribution sub-circuit includes a second switch, a third switch, and a capacitor; a first end of the capacitor is connected to the power source by using the second switch and is connected to the first end of the first switch by using the third switch, a second end of the capacitor is grounded, and the first end of the capacitor is used as an output end of the clock distribution sub-circuits; and connection and disconnection of the first switch is controlled by a first clock signal, connection and disconnection of the second switch is controlled by a second clock signal, and connection and disconnection of the third switch is controlled by a third clock signal.

A clock signal delay path unit includes a first delay cell including a first root signal line for delaying and transmitting a clock signal, a first repeater to transmit the clock signal transmitted through the first root signal line without signal attenuation, and a second root signal line for delaying and transmitting the clock signal output from the first repeater, a second delay cell including a first inverting circuit configured to invert the clock signal provided from the first delay cell to generate an inverted clock signal, and a third delay cell including a first branch signal line for delaying and transmitting the inverted clock signal provided from the second delay cell, a second repeater to transmit the inverted clock signal transmitted through the first branch signal line, and a second branch signal line for delaying and transmitting the inverted clock signal output from the second repeater.
