Abstract

The invention provides a circuit device and an oscillator, which can realize a multi-output function of a clock signal and high-precision duty ratio adjustment. The circuit device includes: an oscillation circuit that generates an oscillation signal by oscillating an oscillator; a waveform shaping circuit to which the oscillation signal is input and which outputs a clock signal obtained by waveform-shaping the oscillation signal; a first duty adjustment circuit that adjusts the duty of the clock signal; and an output buffer circuit that outputs the first output clock signal and the second output clock signal to the outside in accordance with the clock signal. The output buffer circuit includes a second duty adjustment circuit that adjusts the duty of the second output clock signal.

Description

technical field [0001] The present invention relates to a circuit device, an oscillator, and the like. Background technique [0002] Conventionally, a circuit device having an oscillation circuit for oscillating a resonator such as a crystal resonator is known. In such a circuit device, it is desired to increase the precision of the duty ratio of the clock signal generated based on the oscillation signal. For example, Patent Document 1 discloses a CMOS inverter circuit in which, after an input signal is input to an input terminal, a control signal is input to a control terminal of a switch connected to the source of one of the PMOS transistor and the NMOS transistor, thereby maintaining The voltage of the input signal is used to correct the duty ratio of the output signal. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-21388 [0004] However, in the configuration of Patent Document 1, it is difficult to perform accurate duty adjustment of the clock signal....
