Oscillator, oscillating method, image sensor, and imaging apparatus

摘要

An oscillator includes: inverters that are connected in a loop shape and of which the number is an odd number greater than or equal to three; and a delay section that delays change in a voltage which is input to one inverter of the odd number of inverters. The one inverter is a schmitt trigger inverter. The schmitt trigger inverter includes a current source, and a resistor in which current supplied by the current source flows. A hysteresis width of the schmitt trigger inverter depends on the current which flows in the resistor.

1. An oscillator comprising:
inverters that are connected in a loop shape and of which the number is an odd number greater than or equal to three; and a delay section that delays change in a voltage that is input to one inverter of the odd number of inverters, wherein the one inverter is a schmitt trigger inverter, wherein the schmitt trigger inverter includes
a current source, anda resistor in which current supplied by the current source flows, wherein a hysteresis width of the schmitt trigger inverter depends on the current that flows in the resistor, wherein the delay section includes a different current source and a capacitor, and wherein an oscillatory period depends on current, which flows in the capacitor, and the hysteresis width.
