The level-crossing detector controls sampling switches to provide a precise sample of the output voltage when the level-crossing detector senses the predetermined level crossing of the input signal. The level-crossing detection may be a zero-crossing detection. An optional common-mode feedback circuit can keep the output common-mode voltage substantially constant.

Abstract: Described is a switched-capacitor network and method for performing an analog circuit function. The circuit includes a switched-capacitor network, a comparator, and a voltage-offset network. The switched-capacitor network includes multiple switches, each having a respective threshold voltage and connected to one of a high-limit voltage, a low-limit voltage, and electrical ground. A first comparator input terminal in communication with the switched-capacitor network is configured to receive a node voltage therefrom during a first phase. The second input terminal is configured to receive one of the high-limit voltage and the low-limit voltage. The voltage-offset network provides a voltage shift at the first input terminal setting an input reference level at a mid-level voltage with respect to the high-limit voltage and the low-limit voltage. The voltage shift enables the first terminal to receive full-swing voltages when the high-limit voltage is less than twice the threshold voltage, with power supply voltages below twice the threshold voltage.

Abstract: A sample-data analog circuit includes a level-crossing detector. The level-crossing detector controls sampling switches to provide a precise sample of the output voltage when the level-crossing detector senses the predetermined level crossing of the input signal. A multiple segment ramp waveform generator is used in the sample-data analog circuits. The ramp waveform generator includes an amplifier, a variable current source, and a voltage detection circuit coupled to the current source to control the change in the amplitude of the current. The ramp generator produces constant slope within each segment regardless of the load condition. The sample-data analog circuit also utilizes variable bandwidths and thresholds.

Abstract: A switched capacitor circuit includes a first level-crossing detector to generate a level-crossing detection signal when an input signal crosses a first predetermined level. A first waveform generator generates a first predetermined waveform and a second waveform generator generates a second predetermined waveform. A second level-crossing detector generates a second level-crossing detection signal when said second predetermined waveform crosses a voltage reference level a second time. A second switch is coupled to the second level-crossing detector, and a third switch is coupled to the first level-crossing detector. The second switch turns OFF when the second level-crossing detection signal indicates the second predetermined waveform crossed the voltage reference level a second time. The third switch turns OFF when the first level-crossing detection signal indicates the input signal crossed the first predetermined level.

Abstract: Described is a switched capacitor circuit for performing an analog circuit function. Unlike conventional switched capacitor circuits employing operational amplifiers, the switched capacitor circuit uses a comparator and does not require direct feedback between the input and output of the comparator. The switched capacitor circuit includes a first and a second switched capacitance network, a comparator and a current source. The first switched capacitance network has an input terminal to receive a circuit input voltage during a first phase. The comparator has an input terminal in communication with the first switched capacitance network and an output terminal in communication with the second switched capacitance network through a switched terminal. The current source communicates with the switched capacitance networks and supplies a current to charge the networks during a second phase. The circuit can be used, for example, to provide high gain amplification in integrated circuits.
