Abstract
A data-acquisition platform an analog input signal includes a converter that provides activity tokens (36) and circuitry connected to receive the activity tokens from the converter. The converter comprises a level-crossing analog-to-digital converter that generates an activity token when the input signal crosses a quantization level. The circuitry comprises either a delay-line analog filter or an adaptation module configured to cause the converter to adaptively change the quantization levels. WO
Claims20
An apparatus comprising a data-acquisition platform that receives an input signal, said input signal being an analog input signal, said data-acquisition platform comprising a converter that provides activity tokens and circuitry connected to receive said activity tokens from said converter, wherein said converter comprises a level-crossing analog-to-digital converter that generates an activity token when said input signal crosses a quantization level, wherein said circuitry is selected from the group consisting of:
- a filter, said filter comprising a delay-line analog filter configured to cause said converter to adaptively change said quantization levels and an adaptation module configured to cause said converter to adaptively change said quantization levels.
A method comprising receiving an analog input signal, adaptively changing at least one quantization level of a level-crossing analog-to-digital converter, generating an activity token when said input signal crosses said quantization level, and receiving said activity token, wherein adaptively changing said at least one quantization level comprises using a circuit selected from the group consisting of a delay-line analog filter and an adaptation module.
