    Abstract: Disclosed are a proximity sensor and a proximity detection method for the proximity sensor. The proximity sensor includes: a reception circuit configured to receive a first electrical signal which is generated based on proximity of the conductor; a first signal processing circuit configured to determine whether or not the conductor is in close proximity to the electronic device by using the first electrical signal, a first baseline value, and a threshold value; a temperature detection circuit configured to detect the temperature of the proximity sensor independently of the first electrical signal; and a second signal processing circuit configured to, when the conductor is in close proximity to the electronic device and also a temperature variation equal to or larger than a reference value is detected by the temperature detection circuit, generate a second baseline value by adding a temporary compensation value to the first baseline value.

    Abstract: A pulse width modulation (PWM) signal generation circuit and method are disclosed herein. The PWM signal generation circuit includes an integer part pulse generation circuit, and a fractional part pulse generation circuit. The integer part pulse generation circuit generates an integer part pulse using the integer part of the digitized value of a duty cycle, i.e., the ratio of the time during which any one of high and low levels is maintained to the period of a PWM signal. The fractional part pulse generation circuit generates the PWM signal using the integer part pulse and the fractional part of the digitized value of the duty cycle.

    Abstract: Disclosed herein are a Bluetooth signal receiving device and a Bluetooth Smart receiving method. The Bluetooth signal receiving device includes a frequency shift demodulator circuit, a sampler circuit, a training bit pattern discriminator circuit, and a symbol timing offset compensation circuit. The frequency shift demodulator circuit generates a baseband signal by performing frequency shift modulation on a received signal. The sampler circuit samples the baseband signal based on a symbol timing, and generates a plurality of series of bit streams based on sampled values. The training bit pattern discriminator circuit determines whether the plurality of series of bit streams generated by the sampler circuit satisfies a training bit pattern condition. The symbol timing offset compensation circuit compensates the symbol timing of the baseband signal based on a measured error metric as an effective error metric if the plurality of series of bit streams satisfies the training bit pattern condition.
