    • A video signal converter converts a color graphics array (CGA) video signal to a video graphics array (VGA) video signal without a horizontal sync spike. The converter includes an input interface, a conversion circuit and an output interface. The input interface is configured to receive a color graphic array (CGA) video signal. The conversion circuit is configured to convert the CGA video signal to a video graphic array (VGA) video signal. The output interface is configured to output the VGA video signal with a reduced horizontal sync spike. This is necessary for the use of auto-alignment of the LCD display

    • A control circuit suitable for generating control signals for controlling the bit and select lines for a static RAM and also for use in a buffer for reducing transient current and for controlling the slew rate. The circuit comprises a pull up and a pull down transistor, each having a first and a second terminal, and a passing gate connecting the second terminals of the two transistors. The gates of the two transistors are controlled by a signal. A first control signal at the second terminal of the pull up transistor has a fast rise time and slow fall time with respect to the input signal and the second control signal at a second terminal of the pull down transistor has a fast fall time and slow rise time with respect to the input signal. When the control circuit is used for controlling a static RAM, the passing gate is always turned on. The two control signals are then used to control the bit and select lines of the static RAM. When a control signal is used in a buffer comprising a pull up and a pull down transistor, the input signal to the buffer is applied to the gate of the transistors ind the control circuit. The two control signals are applied to the gates of the pull up and pull down transistors of the buffer to reduce transient current.

The two control signals are applied to the gates of the pull up and pull down transistors of the buffer to reduce transient current. In a further improvement, where the buffer includes a second inverter including a second pull up and a second pull down transistor, two feedback paths are employed to control the gates of the two transistors in the second inverter to control the slew rate of the buffer. The passing gate of the control circuit may be turned on or off by an enabling circuit so that if the circuit is implemented in an integrated circuit having input and output pins, the control circuit can be tri-stated so that an output pin may be used as an input pin when the passing gate is disabled.
