A baud rate generator includes a first counter, a timer and a baud rate correcting circuit. The first counter is configured to count bits of an inputted serial data. The timer is configured to measure a time for which the first counter counts a predetermined number of bits based on a reference clock signal. The baud rate correcting circuit is configured to output a baud rate correction value based on the measurement time by the timer such that a baud rate in a serial communication is corrected based on the baud rate correction value.
