摘要： An inverting stage is coupled between a single-ended in-put node and a first differential output node, and a non-inverting stage is coupled between the single-ended input node and a second differential output node. The inverting stage includes at least one transistor with a first current terminal, a second current terminal, and a control terminal, the first current terminal being coupled to the first differential output node and the control terminal being coupled to a single-ended input node. The non-inverting stage includes at least one transistor with a first current terminal, a second current terminal, and a control terminal, the first current terminal being coupled to the second differential output node, and the second terminal being coupled to the single-ended input node. A bias current of the inverting stage is larger than a bias current of the non-inverting stage.

摘要： A mixer stage is provided that mixes a differential input signal with a differential square-wave signal of an oscillator, having a first amplifier element and a second amplifier element, each of which amplifier elements has a first current connection, a second current connection, and a connection for the differential input signal, having four control elements and also a first output and a second output, wherein the four control elements are modulated in pairs by the differential square-wave signal, thereby connecting each second current connection alternately, and in each case individually, to one of the two outputs. The mixer stage has field-effect transistors as amplifier elements whose first current connections are connected to a constant reference voltage. In addition, a method for mixing frequencies that uses this mixer stage is also disclosed.

摘要： The disclosed invention provides a structure and method for improving performance of a phase locked loop by suppressing low-frequency noise produced by a phase detector. This is achieved by up-conversion of the in-band frequency components in the phase difference between reference signal and feedback signal to a higher frequency range where noise performance of a phase detector is improved. The up-converted phase difference is provided to a phase detector that is configured to determine an error signal based upon this phase difference. The error signal is output to a down-converter configured to down-convert the error signal (e.g., back to the original frequency range), thereby intrinsically up-converting the error signal's low-frequency noise (produced by the phase detector), prior to being provided to a filter configured to filter the up-converted noise, thereby resulting in an improved PLL noise performance.

摘要： A method is presented for changing a frequency of a first local oscillator in a receiving system, which has a first receiver with the first local oscillator and a first frequency control element and a second receiver with a second local oscillator and a second frequency control element. The method is characterized in that the following steps are performed during a change in a frequency of the first local oscillator from an actual frequency of the first local oscillator to a target frequency, at which an actual frequency of the second local oscillator lies between the actual frequency of the first local oscillator and the target frequency: turning off the first local oscillator, control of the first frequency control element such that the first frequency control element provides a first base value, assigned to the target frequency, of a frequency control variable, turning on the first local oscillator, and setting of the frequency of the first local oscillator to the target frequency. Furthermore, a receiving system is presented.
