Publication number: 20130264647Abstract: A semiconductor integrated circuit device with a “PAD on I/O cell” structure in which a pad lead part is disposed almost in the center of an I/O part so as to reduce the chip layout area. In the I/O part, a transistor lies nearest to the periphery of the semiconductor chip. When seen in a plan view of the I/O part, a resistance lies above the transistor and a first and a second diode lie above the resistance; a second transistor lies above the diodes; and a logic block lies above the second transistor with a pad lead part, for example, formed in a metal wiring layer, therebetween. This permits the pad through the second transistor to be on the same node and therefore the pad lead part can be disposed almost in the center of the I/O part.Type: ApplicationFiled: June 5, 2013Publication date: October 10, 2013Inventors: Takeo TOBA, Kazuo TANAKA, Hiroyasu ISHIZUKA

Publication number: 20130049864Abstract: An output signal characteristic of a differential amplifier circuit is improved. When an input data signal becomes ‘Low’, current flowing through a first transistor will decrease and potential at a connection (a node) between a first resistor and a second resistor will increase. This potential is input (negatively fed back) to the gate of a second transistor, and because this gate potential increases, a tail current amount is adjusted in an increasing direction. When the input data signal becomes ‘High’, the current of the first transistor increases and thus the potential at the node decreases. Thus, the gate potential (negative feedback) of the second transistor decreases, and the tail current amount is adjusted in a decreasing direction. Thus, in the rising and falling of an input waveform, the difference in a delay time with respect to the output waveform decreases, respectively.Type: ApplicationFiled: August 20, 2012Publication date: February 28, 2013Inventors: Natsuki IKEHATA, Kazuo Tanaka, Takeo Toba, Masashi Arakawa
