摘要： A novel and useful LC-tank digitally controlled oscillator (DCO) incorporating a split transformer configuration. The LC-tank oscillator exhibits a significant reduction in area such that it is comparable in size to conventional ring oscillators (ROs) while still retaining its salient features of excellent phase noise and low sensitivity to supply variations. The oscillator incorporates an ultra-compact split transformer topology that is less susceptible to common-mode electromagnetic interference than regular high-Q LC tanks which is highly desirable in SoC environments. The oscillator, together with a novel dc-coupled buffer, can be incorporated within a wide range of circuit applications, including clock generators and an all-digital phase-locked loop (ADPLL) intended for wireline applications.

摘要： The circuit arrangement generates square-wave signals whose recurrence frequency coincides with the recurrence frequency of input signals supplied to it and whose duty cycle is constant, irrespective of the recurrence frequency. The circuit arrangement contains a flip-flop set by each input signal and reset by reset signals. The square-wave signals are emitted at the output of the flip-flop. A first integrator circuit of relatively great time constant is discharged or charged when the flip-flop is set or reset, respectively. Another integrator circuit is charged whenever the flip-flop is set. The instantaneous voltages at outputs of integrator circuits are compared with each other, and when they are the same the comparator generates the reset signal. In addition, the second integrator circuit is discharged, and renewed charging is prevented as long as the flip-flop is reset.
