PERIOD SIGNAL GENERATION CIRCUITS |
摘要 |
A period signal generation circuit including a control voltage generator and a period controller. The control voltage generator selecting one of temperature-dependent voltages to output the selected temperature-dependent voltage as a control voltage. The first and second temperature-dependent voltages varying according to a temperature and the third temperature-dependent voltage is constant regardless of variation of the temperature. The period controller configured to determine an amount of a current discharging from an internal node in response to the control voltage and outputs a periodic signal whose cycle time is determined according to a level of an internal signal induced at the internal node. |

1. A period signal generation circuit, the circuit comprising:
a drive voltage generator configured to select one of plurality of temperature-dependent voltages to output the selected temperature-dependent voltage as a drive voltage; a discharger configured to discharge charges of an internal node; a level detector configured to compare an internal signal induced at the internal node with a reference voltage to determine a logic level of a periodic signal; and a driver configured to drive a level of the internal node to the drive voltage in response to the periodic signal. |
