    摘要: A protection circuit (100, 700) is disclosed for protecting an integrated circuit having a first supply rail (Vcc) and a second supply rail (Vss) from exposure to an excessive voltage. The protection circuit (100, 700) comprises a sensor (120) for sensing a voltage increase on the first supply rail (Vcc). Such a sensor may be implemented as an RC element. The sensor (120) has an output coupled to a signal path for providing a detection signal on said path. The sensor (120) triggers a clamping circuit (180) to clamp the first supply rail (Vcc) to the second supply rail (Vss) in response to the detection signal, which typically signals an ESD event on the supply rails. A pre-amplifying stage (160) is coupled between the sensor (120) and the clamping circuit (180) to amplify the detection signal for the clamping circuit (180). The protection circuit further comprises a hold circuit (140) for holding the control input of the pre-amplifying stage (160) in an enabled state upon termination of the detection signal. Such a hold circuit may comprise a further RC element for accelerating the activation of the clamping circuit (180) and extending the activation of the clamping circuit beyond the termination of the detection signal, thus yielding a more efficient protection circuit (100, 700).

    摘要: An analog-to-digital converter (ADC1) of the Sigma Delta type provides a stream of digital output samples (OUT) in response to an analog input signal (IN). The analog-to-digital converter (ADC1) comprises a quantizer (QNT) that has a dead zone. The quantizer (QNT) provides a digital output sample that has a neutral value when the quantizer (QNT) receives an input signal whose amplitude is within the dead zone. A feedback path (DAC) within the analog-to-digital converter (ADC1) provides a feedback action only in response to a digital output sample that has a value other than the neutral value.

    摘要: A digitally controlled variable capacitance integrated electronic circuit module (100) comprises a set of basic cells in a matrix arrangement. Each basic cell itself comprises a functional block (11) which can be switched between two individual capacitance values, a control block (12), and a control junction connecting the control block and the functional block of said basic cell. The functional blocks and the control blocks are grouped into separate regions (110, 120) of the matrix arrangement, to reduce capacitive interaction between output paths and power supply paths of the module. The functional blocks can still be switched in a winding path order within the matrix arrangement. A module of the invention can be used in an oscillator capable of producing a signal at 4 GHz.

    摘要: Starting from an input signal (data) and a clock signal (clk), this device supplies an output signal (CKREF0) identical to the input signal but resynchronized with the clock signal. It comprises two cascaded D-type flip-flops (63, 65), the clock signal of the second flip-flop being inverted (62) with respect to that of the first flip-flop. The first flip-flop has its output coupled to the data input of the second flip-flop via a multiplexer (64), which is controlled by a signal (d-Ph) containing information about the phase relationship between the input signal and the clock signal, in such a manner that either input signal or the signal from the first flip-flop is applied to the input of the second flip-flop. This device can be used in a known phase control loop comprising an oscillator whose frequency is controllable, a frequency divider, and a phase comparator.

    摘要: A shrinking-pulse digital delay line (400) has a cascade of a plurality of stages (102,104) for modifying a width of a pulse propagating down the cascade (106 to 118). Each specific one of the stages has an input (106,116), an output (108,118) and a main path (110,112,120,122) between the input and the output. The main path has a first inverter (110,120) and a second inverter (112,122) connected in series via an intermediate node (114,124). Each specific stage has a third inverter (128,140) connected between the input and the intermediate node of a downstream stage in the cascade (102,104); and also has a fourth inverter (132,144) connected between the intermediate node of the specific stage (mode 114, stage 102, mode 124, stage 104) and the output (118, stage 104) of the downstream stage (stage 104).
