摘要： An oscillator circuit comprises a first tank circuit comprising an inductive element and a capacitive element coupled in series between a first voltage rail and a first drive node. A feedback stage is coupled to a first tank output of the first tank circuit and to the first drive node. The feedback stage is arranged to generate, responsive to a first oscillating tank voltage present at the first tank output, a first oscillating drive voltage at the first drive node in-phase with a first oscillating tank current flowing in the inductive element and the capacitive element, thereby causing the oscillator to oscillate in a series resonance mode of the inductive element and the capacitive element.

摘要： An oscillator circuit (100) comprises a first tank circuit (T1) comprising an inductive element (L) and a capacitive element (C) coupled in series between a first voltage rail (14) and a first drive node (12). A feedback stage (F) is coupled to a first tank output (13) of the first tank circuit (T1) and to the first drive node (12). The feedback stage (F) is arranged to generate, responsive to a first oscillating tank voltage present at the first tank output (13), a first oscillating drive signal at the first drive node (12) in-phase with a first oscillating tank current flowing in the inductive element (L) and the capacitive element (C), thereby causing the oscillator (100) to oscillate in a series resonance mode of the inductive element (L) and the capacitive element (C).

摘要： A frequency selective circuit configured to convert an analog input signal to a digital output signal comprises an analog-to-digital converter (44) to generate the digital output signal of the circuit based on an analog input signal to the analog-to-digital converter (44); a digital-to-analog converter (46, 47) to generate an analog feedback signal based on the digital output signal from the analog-to-digital converter (44), and an analog filter arranged to generate the analog input signal to the analog-to-digital converter based on the analog feedback signal and an analog input signal to the circuit. The analog filter comprises at least two integrators (41, 42) in series, each having a feedback path comprising the analog-to-digital converter (44) in cascade with a digital-to-analog converter (46, 47), so that the overall noise transfer function of the circuit has at least two zeros in addition to zeros in the noise transfer function of the analog-to-digital converter.
