    摘要: A driver circuit of a display device, which includes TFTs of a single conductivity type and outputs an output signal with normal amplitude. A pulse is inputted to TFTs 101 and 104 to turn ON the TFTs and a potential of a node α is raised. When the potential of the node α reaches (VDD−VthN), the node α becomes in a floating state. Accordingly, a TFT 105 is turned ON and a potential of an output node is raised as a clock signal becomes High level. On the other hand, a potential of a gate electrode of the TFT 105 is further raised due to an operation of a capacitance means 107 as the potential of the output node is raised, so that the potential of the gate electrode of the TFT 105 becomes higher than (VDD+VthN). Thus, the potential of the output node is raised to VDD without causing a voltage drop due to a threshold voltage of the TFT 105. An output at the subsequent stage is then inputted to a TFT 103 to turn the TFT 103 ON, while the potential of the node α of TFTs 102 and 106 is dropped to turn the TFT 105 OFF. As a result, the potential of the output node becomes Low level.

    摘要: A mode setting circuit for generating a mode setting signal for selecting a particular operational mode in response to an input signal from a mode setting pad. The mode setting circuit includes a driver circuit for generating a mode setting signal in response to an input voltage of a mode setting pad, a first pull-down transistor for discharging a voltage at the mode setting pad, and a second pull-down transistor for discharging the voltage at the mode setting pad in response to a signal from the driver circuit. Such mode setting circuit can prevent a misoperation which may occasionally be caused by ground noises when the mode setting pad is not coupled to the supply voltage terminal. Thus, the reliability of the manufactured goods will be increased.

    摘要: A comparator with a built-in offset is disclosed. The claimed comparator includes a bias current circuit, a differential input stage with the built-in of-set, and a hysteresis circuit. The built-in offset is generated by using a resistor in the differential input stage of the comparator such that the resistor is driven by the bias current as well as the current generated by the hysteresis circuit. Additionally, a reset circuit which uses the comparator with the built-in offset is claimed. The reset circuit uses a voltage divider circuit to divide a first input voltage to the comparator. A band-gap voltage reference is used to provide a second input voltage to the comparator. Therefore, the reset circuit generates a reset signal when the divided voltage reaches the value of the band-gap voltage plus the offset. In another embodiment, a comparator having a differential input stage, an output stage, and a bias circuit with a hysteresis circuit is disclosed. The hysteresis circuit selectively applies a bias voltage to the differential input stage to achieve the hysteresis.

    摘要: In an interface for an input signal with a small amplitude and a high bit rate, the output voltage of a receiver can become more indeterminate when the input signal voltage at the receiving end of a signal transmission line becomes equal to a reference voltage V.sub.ref. In the input buffer circuit of the CMOS current mirror type, a transistor Q.sub.2 is connected in parallel with another transistor Q.sub.1, where the conductivity types of both the transistors are the same and a reference voltage V.sub.ref is applied to the gate electrode of the transistor Q.sub.1. The transistor Q.sub.2 endows the input buffer circuit with a hysteresis characteristic, and the output power N1 of the input buffer circuit is supplied to the gate electrode of the transistor Q.sub.2.
