A touch controller having noise reduction circuitry is disclosed. The touch controller can include a transmit section for generating stimulation signals to drive a touch display to sense a touch or hover event. The touch controller can also include a receive section for processing touch signals from the touch display indicative of the touch or hover event. The touch controller can reduce noise introduced into the stimulation signals and propagated through the touch display into the touch signals, thereby interfering with touch and hover sensing. To reduce the noise, the transmit section's noise reduction circuitry can isolate and subtract some or all of the noise from the stimulation signals. In addition or alternatively, the receive section's noise reduction circuitry can isolate and subtract some or all of the noise from the touch signals.
