    Abstract: For PWM (pulse width modulation), a counter generates a count signal by counting a clock signal 2n times for one period of the count signal. A PWM circuit generates a PWM signal from an n-bit pulse code modulation (PCM) data. The PWM signal includes a first pulse and a second pulse that are symmetric within one period of the count signal for positive and negative values of the n-bit PCM data. A same pulse width for the first and second pulses is determined by a respective value of each bit of the n-bit PCM data excluding the most and least significant bits of the n-bit PCM data.
