    摘要: A test structure (10) is provided for allowing a parametric test system, for example towards the end of a production line at a foundry, to measure the junction leakage of a semiconductor device such as an integrated circuit. The structure is formed as part of the device and comprises a MOSFET (3) whose source and drain are provided with connections (5 and 7) which are accessible to the tester for biasing the device and measuring the drain current. A capacitor (1) is connected between the gate of the MOSFET (3) and another connection (4) allowing the tester to supply various voltages to the connection (4). A junction diode (2) is connected between the gate of the MOSFET (3) and the body terminal and connection (6). During testing, the parametric tester supplies a voltage to the connection (4) to allow the capacitor 1 to be charged via the forward-biased diode (2). The connection (4) is then connected to another voltage such that the diode (2) becomes reverse-biased and its leakage current discharges the capacitor (1) so that the voltage on the gate of the MOSFET (3) falls. The drain current thus falls and the junction leakage through the diode (2) can be determined from the rate of change of the drain current and knowledge of the transfer characteristic of the MOSFET (3) and the capacitance of the capacitor (1).

    摘要: In-phase and quadrature baseband analog signals are supplied from a tuner front end (1-7) to respective sample and hold circuits (10, 11) which sample their input signals at different times. The resulting samples are converted by a single ADC (13) and the I or Q digital samples are supplied to an interpolator (20-26). The interpolator performs interpolation on (in this case) the Q digital samples to obtain further samples at the same sampling points as the I signal. The resulting samples are supplied to a digital demodulator (28).

    摘要: A digital television converter (1) is provided, for example for performing all of the functions of a set top box for receiving digital terrestrial or satellite television broadcast signals. The converter (1) comprises a SCART connector (2) for mating with a mating connector (28) on a television apparatus, such as a television receiver (21) or a VCR (22), which is incapable of reception of digital television broadcasts. This connection provides electrical contact with the apparatus (21) and provides mechanical support for the converter (1). The converter also comprises a tuner (12) which selects and demodulates a television channel for reception and supplies to the connector (2) signals in a form suitable for use by the television apparatus (21). A connector rear housing (3) completes the enclosure for the converter (1) containing the tuner (12).

    摘要: An amplifier, for example for use as an LNA of a radio frequency tuner, comprises a differential amplifying stage (1-5) provided with an AGC core (6-9). The output signals are formed across load resistors (10, 11) at differential outputs (OUT+, OUT-). Compensating stages (15, 16) sum the signals at the differential outputs (OUT+, OUT-) and subtract the resulting sum signal from the output signals so as to cancel the common mode signals including second order distortion products.

    摘要: An LNA for use as an input stage of a radio frequency tuner comprises an inverting amplifier stage (1) and a transconductance stage (6). The amplifier stage (1) has an input connected via an input resistance (2) to an input (3) of the amplifier and via a feedback resistance (4) to an output of the amplifier stage (1). The transconductance stage (6) passes a current through the input resistance (2) which is substantially proportional to the output voltage (Vout) of the amplifier stage (1).
