摘要： A television receiver has an a.f.c. arrangement for ensuring the correct tuning of a tuner unit (4) which is tuned to the nominal carrier frequency by a tuning voltage (VT). When the tuner unit (4) is incorrectly tuned to the actual carrier frequency the a.f.c. system operates in a first mode in which a sweep current produced by a current source (15) is applied by way of a closed switch (16) to an a.f.c. capacitor (17) to produce a swept a.f.c. voltage for the tuner unit (4). The sweep direction is controlled by an RS flip-flop (13) by way of a multiplexer (12) in response to voltage comparators (19, 20) connected to the a.f.c. capacitor (17). When the tuning is sufficiently close such that the received transmission can be correctly decoded the a.f.c. arrangement goes into a second mode in which the output of a frequency demodulator (6) is applied via multiplexer (12) to control the current source (15) and hence the voltage across a.f.c. capacitors (17). For this second mode gate pulses (G1, G2) from a data processor (11) control the multiplexer (12) paths via a monostable (14) and only cause switch (16) to be conductive during a given portion of each line period.

摘要： A speed control system for an a.c. electric motor (1) comprises a microcomputer (6) to an interrupt signal input ( INT /TO) of which are coupled the outputs of a detector (10) for zero-crossings in the a.c. supply and a tachogenerator (11) connected to 'the motor. The microcomputer supplies firing pulses to a triac (2), included in series with the motor, in response to an overflow of a clocked counter (CT), this counter being suitably preloaded at each zero-crossing. The counter is read each time a tachogenerator pulse occurs and the time which this reading indicates has elapsed since the immediately preceding zero-crossing is stored. A record is also kept in a register (ZCSLTA) of how many zero-crossings occur between each tachogenerator pulse and the next and from this and the stored times relating to the relevant pulses the period of the tachogenerator pulses and hence the actual speed of the motor is calculated. The preloading value for the counter is calculated from this and the required speed.

摘要： A method of manufacturing a semiconductor device including both an enhancement (1) insulated gate field effect transistor (IGFET) and a depletion (2) mode IGFET is described. Impurities are introduced into a first region or epitaxial layer (4) of one conductivity type adjacent a given surface (3a) of a semiconductor body (3) to provide, for both the enhancement mode (1) and for the depletion mode (2) IGFET, a second region (5) of the opposite conductivity type adjacent the given surface, a source region (9) of the one conductivity type adjacent the given surface (3a) and surrounded by the second region (5) and a drain region (10) of the one conductivity type having a relatively lowly doped drain extension region (11)adjacent the given surface and extending towards the source region (9). First and second insulated gates (12) are provided on first and second areas (31a) and (31b), respectively of the given surface to provide a respective gateable connection between each source region (a) and the associated drain region (10). The relative doses of impurities introduced to provide the second regions (5) and the relatively lowly doped drain extensions (1) received by the first area (31a) and the second area (31b) are independently controlled so as to provide adjacent the first area (31a) a channel area (13) of the opposite conductivity type and adjacent the second area (31b) a channel area (13′)of the one conductivity type.

摘要： An arrangement for driving a semiconductor device ( 1 ) has an input (12) for receiving a control signal and a control output (11) for connection to the control electrode (9) of a power semiconductor device ( 1 ) which is connected in series with a load (5) across a power supply (3,6). The arrangement includes an active turn-off device (T67) to achieve fast turn-off of the device ( 1 ). The arrangement further includes a threshold detecting means ( 29 ) which operates to turn on the semiconductor device ( 1 ) in the event of a high voltage transient on the power supply. This reduces the voltage across the semiconductor device and hence reduces power dissipation within the semiconductor during transients. The turn-off device (T67) could be damaged by high transient currents when the threshold detecting means ( 29 ) conducts, so a further threshold detecting means ( 30 ) acts to disable the turn-off means (T67) during transients. The arrangement may be integrated monolithically with an associated semiconductor output device. An intelligent power switch circuit including such an arrangement is suitable for use in a motor vehicle.

摘要： A differential amplifier comprises first and second matched field-effect transistors (FETs) (21,22) having their source electrodes connected together and to a current source ( 2 ), and their drain electrodes connected respectively to an input and an output of a current mirror circuit ( 3 ). The FETs (21,22) are depletion-mode FETs, and the current source comprises parallel-connected third and fourth depletion-mode FETs (25,26) matched to the first and second FETs (21,22). The current source ( 2 ) and current mirror ( 3 ) act to constrain the first and second FETs (21,22), to operate over a predetermined operating curve, for which they are optimally matched to one another. The differential amplifier may be constructed as an integrated circuit, and may form part of a circuit for sensing current in a power semiconductor device.

摘要： A precoded duobinary signal is applied to first inputs of two voltage comparators (CP1, CP2) whose second inputs receive reference voltages appropriate to required slicing levels. The output of each comparator (CP1, CP2) is applied to respective inputs of an exclusive NOR gate (G) the output of which provides a binary signal dependent on the duobinary signal input. This duobinary input is also applied to peak rectifier circuits (D1, C1; D2, C2) whose outputs are connected to respective ends of a voltage divider (R1, R2, R3) from which the reference voltages for the comparators (CP1, CP2) are derived.
