Latest Patents
Chowdhury's latest patents include a capacitive touch sense architecture that employs a correlator for demodulating a measured capacitance from an excitation signal. This innovative analog front end circuit utilizes coherent detection within a capacitance measurement application. The circuit is designed to measure the capacitance of a touch screen display effectively. An analog excitation signal is modulated by the capacitor being measured. The modulated signal is then synchronously demodulated using a correlator, which consists of a discrete mixer and a discrete integrator. The excitation signal is also input to the mixer, allowing the modulated signal to be multiplied by the excitation signal. This excitation signal can take the form of an analog signal with a sine wave function or other waveforms.
