摘要： An integrated circuit is provided with a distributed supply voltage monitoring system in which a single controller controls a plurality of voltage monitors located in respective modules of the integrated circuit. The controller and each circuit form a successive approximation analogue to digital converter. Such a system enables a small size monitoring circuit to be realised for every module of the integrated circuit.

摘要： Power supply connections to an integrated circuit are tested. The power supply connections are connected to a power supply conductor in the integrated circuit. For the test, combinations of current drawing circuits are switched on near the point where the power supply connection under test is connected to the power supply conductor. The current drawing circuits draw a considerable current, so as to cause a detectable voltage drop over the power supply connection, if this connection is operational. Different subsets of the current drawing circuits are activated successively. To prevent that all of the current drawing circuits are switched on at the same time by error, activation of each subset is controlled by a signal indicative of completion, of activation of the preceding subset. A respective signal line is provided for each subset, to provide the signal for the subset.

摘要： An integrated circuit (1) comprises a voltage sensing circuit (2) and a current mirror (3) for sensing both a voltage (Vi) and a current (Ii) at one input terminal (T) of the integrated circuit. The voltage sensing circuit (2) comprises an input connected to the input terminal (T) and an output supplying a voltage level indication (Vu). The current mirror (3) has an input also connected to the input terminal (T), a reference terminal connected to a reference potential, and an output supplying an output current (Iu). The input of the current mirror has a high impedance as long as the voltage level (Vi) is below a threshold voltage (Vth) of the current mirror (3). Within a voltage range determined by this threshold voltage (Vth), the voltage level indication (vu) is a measure of the voltage level (Vi). The current mirror (3) becomes active and the output current (Iu) is a mirrored input current (Ii) if the voltage level (Vi) exceeds the threshold voltage (Vth). The threshold voltage may be determined by an input transistor (T1) of the current mirror (3). This input transistor (T1), which is arranged as a diode, starts conducting if the voltage level (Vi) reaches the threshold voltage (Vth) of this diode.

摘要： An integrated circuit (IC) includes circuitry in a plurality of power domains for transmitting and/or receiving radar chirp frames and first and second monitoring systems for monitoring supply voltages of a first and a second subset of the plurality of power domains, respectively. The first subset is monitored outside of a time window during which a chirp frame is transmitted and/or received utilizing circuitry of the IC, and the second subset is monitored during the time window. The first monitoring system includes an output for an error signal indicating a supply voltage in the first subset does not comply with a first voltage parameter. The second monitoring system includes a unique monitoring circuit for each power domain in the second subset, and each unique monitoring circuit includes an output for an error signal indicating a supply voltage in the second subset does not comply with a second voltage parameter.
