Receivers and methods of testing are described. A receiver includes a plurality of receiver channels, each including an amplifier for receiving a signal from an antenna and a mixer downstream of the amplifier. A test signal generating circuit is configured to generate test signals. A signal path connects the test signal generating circuit and each receiver channel and couples to each receiver channel at a coupling between the amplifier and a mixer. A test signal from the test signal generating circuit is injectable to the parts of the receiver channel downstream of the amplifier. The test signal may alternatively be injected into the entire receiver channel. The receivers and methods may be used in wireless systems, such as radar systems and radio systems.

Receiver testing

The invention provides a testing circuit for testing a connection between a chip and external circuitry. A current source is used to inject a DC current towards the connection to be tested from the chip side. On-chip ESD protection is provided giving a path between the connection to be tested and a fixed voltage line. A shunt path is also coupled to the connection to be tested on the external circuitry side. It is determined if the current source current flows through the ESD protection circuit, and this can be used to determine whether or not the connection to be tested presents an open circuit for the DC test current.
