    摘要: Examples are provided for converting an analog signal to a digital output signal using serial-ripple analog-to-digital conversion (ADC). An ADC circuit may include conversion stages coupled in series. Each conversion stage may generate a bit for the digital output signal. A data latch may receive bits for the digital output signal from the conversion stages and to provide the digital output signal based on the bits. A conversion stage may include a comparator circuit and a multiplexer circuit. The comparator circuit may compare a sampled input signal with a reference signal and to generate the associated bit of the digital output signal based on a result of the comparison. The multiplexer circuit may provide an associated reference signal to a comparator circuit of a next conversion stage, where the next conversion stage is subsequent to the conversion stage.

    摘要: Examples of resistive digital-to-analog converter (RDAC) circuits are provided herein. RDAC circuits may provide an analog output signal derived from an n-bit digital input signal. In one example, an RDAC circuit may include a plurality of resistive circuit branches. Each resistive circuit branch may be arranged in a pull up/pull down network configuration. For example, an RDAC circuit may include a plurality of resistive circuit branches positioned in parallel. In an example, each of the plurality of resistive circuit branches may include a first inverter circuit, a second inverter circuit, and a resistive component. The RDAC circuit may include an output node for providing the analog output signal. Additionally, methods are provided for converting an analog output signal derived from an n-bit digital input signal.
