摘要： A one-coil multi-core inductor-capacitor (LC) oscillator is provided. The one-coil multi-core LC oscillator includes a main coil and at least one mode suppression device. The main coil includes an outer wire and a central wire, wherein the outer wire is coupled to a first core circuit and a second core circuit, and the central wire is coupled between a first node and a second node of the outer wire. More particularly, an outer loop formed by the outer wire corresponds to a first mode of the one-coil multi-core LC oscillator, and inner loops formed by the outer wire and the central wire correspond to a second mode of the one-coil multi-core LC oscillator, where the at least one mode suppression device is configured to suppress one of the first mode and the second mode.

摘要： A drive circuit and a memory chip are provided. The drive circuit includes: an amplification module, working under a first voltage domain; an output module, working under a second voltage domain, a power supply voltage of the second voltage domain being greater than a power supply voltage of the first voltage domain, and an output terminal of the output module being an output terminal of the drive circuit; a connection module, connected to an output terminal of the amplification module and an input terminal of the output module; and a feedback module, an input terminal of the feedback module being connected to the output terminal of the output module, and an output terminal of the feedback module being connected to an input terminal of the amplification module. The embodiments of the present disclosure can improve the accuracy of the output voltage of the drive circuit by employing the output terminal and inputout terminal of the drive circuit that are working at two voltage domains respectively and the feedback module, so that the power consumption of the drive circuit is reduced.
