According to one embodiment, a method of operating a switched capacitor circuit includes: precharging a capacitor using a voltage buffer having an input coupled to an input node of the switched capacitor circuit and an output coupled to the capacitor; coupling the input node to a capacitor, wherein the first charge is collected on the capacitor; and the first charge is integrated using an integrator.
Description
technical field [0001] The present invention relates generally to electronic circuits and, more particularly, to systems and methods for switched capacitor circuits. Background technique [0002] Analog-to-digital converters are commonly used in many electronic applications to convert analog signals to digital signals. In the real world, most data or signals are represented by analog signals such as temperature, sound, light, pressure, etc. These analog signals, which are continuous in time and amplitude, are converted by an ADC into digital signals which are discrete with respect to time and quantized with respect to amplitude. ADC architectures vary based on end application, cost, speed and resolution. Various types of ADCs include, for example, flash ADCs, Delta-sigma ADCs, successive approximation ADCs, and dual-slope ADCs. [0003] One common application that is increasingly using ADCs is the automotive industry. For example, an ADC may be used to digitize analog si...
