摘要： The invention relates to a buffer circuit for a receiver device including a transconductance stage and an output stage coupled in parallel to output stages of other channels of the device. The output of the transconductance stage is connected to a base of a bipolar transistor in the output stage. A switch is connected between the base of the bipolar transistor and the emitter of the bipolar transistor. A controller is arranged to switch the buffer circuit from a switch-off mode to a switch-on mode and back. In switch-off mode the switch is switched on, so as to connect the base and the emitter of the bipolar transistor.

摘要： An electronic device has a capacitive arrangement for controlling a frequency characteristic. The capacitive arrangement has varactor banks having a number of parallel coupled varactors and a control input for switching the respective varactors on or off. A main varactor bank has N varactors and a series varactor bank has A varactors, the main varactor bank being connected in series with the series varactor bank. A shunt varactor bank of B varactors may be coupled to a ground reference and connected between the main varactor bank and the series varactor bank. When a varactor is switched in the main varactor bank, it provides an equivalent capacitance step size (or frequency step) smaller than size of a capacitance step when switching a single varactor on or off. According to the number of varactors selected in the shunt varactor, B, this frequency step can be made programmable. By the arrangement of unitary varactors a very small step size is achieved for providing a high resolution of frequency of a digitally controlled oscillator.
