Abstract:
A starter circuit comprising:a voltage generating unit, including a first resistor, a second resistor, a third resistor, and a first transistor, connected in series between a first power supply line and a second power supply line, said first transistor being connected at its gate to a connection node of said second and third resistors, and said voltage generating unit generating a first voltage at a first node where resistive division is made by said first and second resistors; a starter signal generating unit including a fourth resistor and a second transistor having its gate connected to said first node, connected in series between said first power supply line and said second power supply line, which generates a second voltage at a second node connecting said fourth resistor with said second transistor; and a waveform shaping unit for shaping a waveform of the voltage of said second node and outputting the shape waveform as a starter signal that initializes an internal circuit of an integrated circuit.
