Abstract
The semiconductor integrated circuit includes a first transistor which flows a current from a high voltage source to a first node, a second transistor which flows a current from the first node to a low voltage source. Furthermore, a first inverter receives an input signal and drives the first node based on this input signal, and a second inverter drives a second node based on a voltage of the first node.
Claims19
A semiconductor integrated circuit comprising:
- a first element connected between a first node and a first voltage line applied with a first voltage, for flowing a current from the first voltage line to the first node;
- a second element connected between the first node and a second voltage line applied with a second voltage lower than the first voltage, for flowing a current from the first node to the second voltage line;
- a first inverter having its output connected to the first node, for changing a voltage of the first node in a direction opposite to a direction of a voltage change of an input signal in response to the voltage change of the input signal;
- and
- a second inverter having its output connected to the second node, for changing a voltage of the second node in a direction opposite to a direction of a voltage change of the first node in response to the voltage change of the first node.
