Abstract
Various approaches of receiving signals in integrated circuitry include implementing two successive stages of signal manipulation and employing an interface having an AC coupling network and buffer circuits for decoupling the output impedance and common-mode level of the first stage of signal manipulation from the input impedance and common-mode level of the second stage of signal manipulation without degrading the performance of either stage.

A sensor for receiving signals in integrated circuitry, the sensor comprising:
- circuitry for applying at least two successive stages of manipulation to the received signals;
- and
- an interface comprising an AC coupling network and buffer circuits for decoupling an output impedance and a first common-mode level of a first one of the two successive stages from an input impedance and a second common-mode level of a second one of the two successive stages without degrading the performance of either stage.
An NMR apparatus comprising:
- an NMR coil configured to enclose a sample;
- a receiver for receiving NMR signals from the sample, the receiver comprising (i) circuitry for applying at least two successive stages of manipulation to the received NMR signals, and (ii) an interface comprising an AC coupling network and buffer circuits for decoupling an output impedance and a first common-mode level of a first one of the two successive stages from an input impedance and a second common-mode level of a second one of the two successive stages without degrading the performance of either stage;
- and
- a controller configured to analyze the received NMR signals.
A method of receiving signals in integrated circuitry, the method comprising:
- providing at least two successive stages of signal manipulation;
- and
- providing an interface for decoupling an output impedance and a first common-mode level of a first one of the two successive stages from an input impedance and a second common-mode level of a second one of the two successive stages without degrading the performance of either stage.
