摘要： A method and apparatus for performing calculations relating to the derivation of log-likelihood ratio (LLR) is provided. Coefficients in the use of deriving LLRs are calculated the calculation being applicable to any one of a plurality of constellation diagrams (PAM, QAM, PSK). The coefficients may be stored in a table of coefficients, the table corresponding to a particular constellation diagram and modulation scheme. A number of tables may be stored, each table corresponding to a particular modulation scheme. The coefficients are related to a symbol estimated to be closest to the received sample and the closest symbol to the estimated symbol having a complementary value for a bit for which the LLR is to be calculated. Certain coefficients or parts of coefficients may be omitted where the corresponding constellation diagram has symmetries.

摘要： The present application relates to a near field communications (NFC) reader which includes an amplifier that drives an antenna. Capacitors of fixed value are connected in series between differential outputs of the amplifier and inputs of the antenna and form a series resonant circuit with the impedance of the antenna. Variable capacitances are provided in series with the fixed value capacitors, and the capacitance of these variable capacitances can be adjusted to compensate for manufacturing tolerances in the fixed value capacitors which cause a frequency offset between a desired resonant frequency of the series resonant circuit its actual resonant frequency, and to compensate for changes in the input impedance of the antenna that occur as the distance between the antenna of the reader and an antenna of an NFC tag changes.

摘要： A non-volatile memory cell that includes a semiconductor substrate; a coupling capacitor located in a first active region of the semiconductor substrate; and at a shared second active region of the semiconductor substrate, a sense transistor and a tunnelling capacitor configured in parallel with the gate of the sense transistor. The coupling capacitor, sense transistor and tunnelling capacitor share a common floating gate electrode and the sense transistor includes source and drain regions arranged such that the tunnelling capacitor is defined by an overlap between the floating gate electrode and the drain region of the sense transistor. Word-line contacts may be to a separate active area from the coupling capacitor. This and/or other features can help to reduce Frenkel-Poole conduction.
