Abstract
A latch-type level converter has a signal-input transistor, a latch, and a clock-input transistor. The signal-input transistor, which is a high-voltage transistor, receives an input signal, and the latch holds data of the input signal received by the signal-input transistor. The clock-input transistor controls the operation in accordance with a clock. According to the latch-type level converter, not only can low-amplitude signals be accurately amplified, but also input signals having a common-mode voltage higher than the supply voltage can be received.
