Module circuit and reservoir circuit

A module circuit comprising:

• a first block circuit;
• and
• a second block circuit,
• wherein the first block circuit includes a first input terminal into which an input pulse signal is input, a holding unit that holds an average value of the input pulse signal for a predetermined period according to an interval of the input pulse signal and a width of the input pulse signal, an oscillation unit that generates an output pulse signal at a frequency according to the average value, and a first output terminal that outputs the output pulse signal,
• the second block circuit includes a second input terminal to which the output pulse signal output from the first block circuit is input, a duty ratio adjuster that adjusts the duty ratio of the output pulse signal, and a second output terminal that outputs the output pulse signal adjusted by the duty ratio adjuster,
• in the first block circuit, the holding unit includes a capacitor, integrates a pulse voltage indicating the input pulse signal, and holds a result of integrating the pulse voltage as the average value,
• the oscillation unit is supplied with an integrated current, which is obtained by integrating the pulse voltage with the holding unit and increases monotonically with respect to the result of integrating the pulse voltage, from the holding unit, and generates the output pulse signal with a frequency that depends on a magnitude of the integrated current, and
• a high side switching element that forms the pulse voltage charged to the capacitor by opening and closing according to the input pulse signal indicating an excitatory input is further included.
