摘要： An amplifier for converting a single-ended input signal to a differential output signal. The amplifier comprises a first transistor, a second transistor, a third transistor and a fourth transistor. The first transistor, configured in common-source or common-emitter mode, receives the single-ended input signal and generates a first part of the differential output signal. The second transistor, also configured in common-source or common-emitter mode, generates a second part of the differential output signal. The third and fourth transistors are capacitively cross-coupled. The amplifier further comprises inductive degeneration such that a source or emitter of the first transistor is connected to a first inductor and a source or emitter of the second transistor is connected to a second inductor.

摘要： A switched mode power supply comprises a control signal generator arranged to generate first and second control signals via first and second outputs, respectively, which are coupled to respective first and second inputs of a switching stage, by means of respective first and second control signal paths. The switching stage is arranged to, responsive to the first and second control signals, alternately charge and discharge the reactive element by coupling it alternately to first and second supply voltages. An adjustable delay stage in one of the first and second signal paths is arranged to control an adjustable delay so that a first delay experienced by the first control signal passing from the control signal generator's first output to the switching stage's first input is substantially equal to a second delay experienced by the second control signal passing from the control signal generator's second output to the switching stage's second input.

摘要： A switched mode power supply (100) comprises a reactive element (10) and a control signal generator (30) is arranged to generate a first control signal at a first output (31) of the control signal generator (30) and a second control signal at a second output (32) of the control signal generator (30). The first output (31) of the control signal generator (30) is coupled to a first input (21) of a switching stage (20) by means of a first control signal path (40) and the second output (32) of the control signal generator (30) is coupled to a second input (22) of the switching stage (20) by means of a second control signal path (50). The switching stage (20) is arranged to, responsive to the first and second control signals, alternately charge and discharge the reactive element (10) by coupling it alternately to first and second supply voltages. A delay detector (60) is arranged to generate a delay indicator signal indicative of a relative delay between the first control signal at the first input (21) of the switching stage (20) and the second control signal at the second input (22) of the switching stage (20). An adjustable delay stage (53) in one of the first and second signal paths (40, 50) is arranged to, responsive to the delay indicator signal, control an adjustable delay so that a first delay experienced by the first control signal passing from the first output (31) of the control signal generator (30) to the first input (21) of the switching stage (20) is substantially equal to a second delay experienced by the second control signal passing from the second output (32) of the control signal generator (30) to the second input (22) of the switching stage (20).
