摘要： An integrated circuit comprises a receiver and an oscillator circuit. The receiver has a first input port for receiving a first oscillatory input signal, a second input port for receiving a second oscillatory input signal, and an output port for delivering an oscillatory output signal which is a function of both the first input signal and the second input signal. The oscillator circuit has a first output port for delivering a first oscillatory signal, and a second output port for delivering a second oscillatory signal. The first output port of the oscillator circuit is coupled to the HF port, and the second output port of the oscillator circuit is coupled to the LO port. The integrated circuit may be designed such that the HF port may be disconnected from the first output port of the oscillator circuit without affecting the operability of the receiver. An apparatus for testing the proper functioning of an integrated circuit as described above and a method of producing a receiver are also disclosed. The method may facilitate testing a receiver die during production. In particular it may avoid the need for feeding high-frequency signals from an external apparatus to the die.

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.
