Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A period signal generation circuit, the circuit comprising: a control voltage generator configured to select one of plurality of temperature-dependent voltages to output the selected temperature-dependent voltage as a control voltage; and a period controller configured to determine an amount of a current discharging from an internal node in response to the control voltage and to output a periodic signal having a cycle time that is determined according to a…
