Title: Class-D amplifier circuits
Inventor: JOHN PAUL LESSO
IPC: H03F3/217
Filed: 2013-10-23
Abstract: A class-D amplifier circuit includes an output stage 101 having at least first and second switches, a modulator 104 and a frequency controller 301. The modulator has a switching cycle frequency based on a received first clock signal FIN, and controls the duty cycles of the first and second switches within the switching cycle based on a received input signal, e.g. audio. A reference waveform generator 302 in the modulator generates a ramped reference waveform at a frequency based on the first clock signal. In response to an indication of the amplitude of the input signal, which may be from the input signal SIN, volume control VOL, envelope value, or modulator output (Fig.16), the frequency controller controls the first clock signal to provide first and second switching frequencies fSW, where a lower switching frequency is provided at the second, lower, input signal amplitude. The frequency controller is configured such that switching frequency transitions are substantially synchronised to the top or bottom of the ramped reference waveform (Fig. 7). Switching losses in a class-D audio amplifier are reduced by reducing the switching frequency at low signal amplitudes, and output signal transients, or undesirable artefacts, caused by a switching frequency transitions are reduced by synchronising transitions to the ramped reference signal peaks (Figs. 8a & 8b).

IPC: G06F3/044
Filed: 2018-09-07
Abstract: A touch display device, a touch circuit, and a touch sensing method include supplying a touch driving signal to a plurality of touch electrodes via a plurality of touch lines that are electronically connected to the plurality of touch electrodes during a display driving period of a touch display device when an image is displayed on the display panel. Sensing the presence or absence of a touch on the display device is based on a difference between two sensing signals received from touch electrodes. The sensing signals may be received in response to a touch driving signal. The touch display device may further include a plurality of data lines and a plurality of gate lines. By performing differential sensing on touch electrodes, noise components which the touch electrodes receive from display electrodes (e.g., data line, gate line, etc.) may be removed to accurately sense a touch, so that display driving and touch sensing may be performed simultaneously. A differential amplifier can be used to provide an output based on received touch electrode signals. In this manner, the display driving and the touch sensing may be normally performed concurrently, thereby enabling implementation of a high-resolution display.
