Abstract
The present application relates to an EQ circuit, a method of operating it and a system comprising the EQ circuit and an ADC. The EQ circuit has a configurable load section, which is provided for selectively exposing one of a plurality of distinct loads to a reference source connected to a reference voltage signal input of the equalization circuit, and a logic section, which is arranged to accept a state signal from the ADC and to selectively connect one distinct load out of the plurality of distinct loads in response to the state signal. The state signal is indicative of an actual operation state of the ADC.

An equalization circuit, comprising:
- a configurable load section comprising a plurality of distinct effective loads, each effective load configured to be selectively connected to a reference voltage signal input of a reference source,
- a logic section arranged to accept a state signal from an analog-to-digital converter (ADC) connected to the reference source and to selectively connect one effective load out of the plurality of distinct effective loads in response to the state signal,
- wherein the state signal is indicative of an actual operation state of the ADC.
A system, comprising
- an analog-to-digital converter, ADC;
- and
- an equalization circuit comprising:
- a configurable load section comprising a plurality of distinct effective loads, each effective load configured to be selectively connected to a reference voltage signal input of a reference source,
- a logic section arranged to accept a state signal from the ADC connected to the reference source and to selectively connect one effective load out of the plurality of distinct effective loads in response to the state signal,
- wherein the state signal is indicative of an actual operation state of the ADC.
A method of operating an equalization circuit, said method comprising:
- providing a plurality of distinct effective loads, each effective load configured to be selectively connected to a reference voltage signal input of a reference source;
- accepting a state signal from an analog-to-digital converter, ADC, connected to the reference source;
- and
- selectively connecting one effective load out of the plurality of distinct effective loads in response to the state signal, wherein the state signal is indicative of an actual operation state of the ADC.
