Abstract: A complementary output generator (COG) module generates at least two complementary outputs determined by rising and falling event sources. In a simple configuration of the COG module, the rising and falling event sources are the same signal which is a signal having the desired period and duty cycle. The COG module converts this single signal input into dual complementary outputs. The frequency and duty cycle of the dual outputs substantially match those of the single input signal. Blanking and deadband times may be introduced between the complementary outputs, and the dual complementary outputs may also be phase delayed. In addition the COG module may provide up to four outputs for controlling half and full-wave bridge power applications.

Abstract: A microcontroller measures capacitance of capacitive sensors having guard rings associated therewith. A guard ring is provided around each capacitive sensor plate and is charged to substantially the same voltage as a voltage on the associated capacitive sensor plate. The guard ring reduces parasitic capacitances of the capacitive sensor plate caused by differences in voltage potentials between the capacitive sensor plate, and adjacent circuit conductors, ground planes and power planes. An analog output is buffered and coupled to an analog input coupled to the capacitive sensor plate, and is used to drive the guard ring voltage to substantially the same voltage as the voltage on the capacitive sensor plate.

Abstract: A slope compensation module provides slope compensation of a switched-mode power supply using current mode control. The slope control unit comprises a capacitor coupled between an input and an output of the slope control unit, a switch for discharging the capacitor and a constant current source for charging the capacitor. Slope compensation parameters may be changed during operation with a programmable constant current source. The slope compensation module may also function as an analog sawtooth waveform frequency generator, and as an analog pulse width modulation (PWM) generator. Charging the capacitor generates a linearly decreasing (negative slope) ramp voltage for modulating a feedback error voltage into a slope compensated feedback error voltage. Capacitor charging may be controlled from a pulse width modulation signal. Opening of the switch may be programmably delayed, and a minimum closed time thereof may also be programmed during operation of the slope compensation module.

Abstract: An analog-to-digital (ADC) controller is used in combination with a digital processor of a microcontroller to control the operation of capacitance measurements using the capacitive voltage division (CVD) method. The ADC controller handles the CVD measurement process instead of the digital processor having to run additional program steps for controlling charging and discharging of a capacitive touch sensor and sample and hold capacitor, then coupling these two capacitors together, and measuring the resulting voltage charge thereon in determining the capacitance thereof. The ADC controller may be programmable and its programmable parameters stored in registers.
