摘要： An integrated circuit (10) comprises a receiver (12) and an oscillator circuit (36, 42). The receiver has a first input port (HF port) (14) for receiving a first oscillatory input signal, a second input port (LO port) (16) for receiving a second oscillatory input signal, and an output port (18) for delivering an oscillatory output signal (IF signal) which is a function of both the first input signal and the second input signal. The oscillator circuit has a first output port (36) for delivering a first oscillatory signal (HF signal), and a second output port (42) for delivering a second oscillatory signal (LO signal). The first output port (36) of the oscillator circuit is coupled to the HF port (14), and the second output port (42) of the oscillator circuit is coupled to the LO port (16). The integrated circuit may be designed such that the HF port (14) may be disconnected from the first output port (36) of the oscillator circuit without affecting the operability of the receiver (12). An apparatus for testing the proper functioning of an integrated circuit (10) 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： A receiver system and method for receiver testing Abstract A receiver system (100) which may be implemented in an integrated circuit device (101) and suitable for use in automotive radar systems (201) such as collision avoidance systems, includes self test circuitry whereby a local oscillator test signal is generated by an on-board frequency multiplier (126) and mixed in a down-conversion mixer (106) with an RF test signal. The RF test signal is generated on the device (101) by up-conversion of an externally generated low-frequency test signal with the local oscillator test signal. Baseband components may also be checked using test signals of suitable frequency divided down from the local oscillator test signal by a programmable frequency divider (130). This self test arrangement obviates any need for applying externally generated RF test signals to the IC device.
