    摘要： The invention discloses a voltage source converter and a voltage source converter system. The voltage source converter comprises: a multi-level voltage source converter, being adapted to output a multiple levels of a first voltage at one of two first output terminals through a multiple of first conducting paths; a first energy store; and a first switching element, being arranged to directly connected with the first output terminal, and being adapted to switch the first energy store in or out of the first conducting path so as to combine a level of the voltage of the first energy store with the level of the first voltage as a second voltage output at a second output terminal. By having the topology as above, the voltage class of each of the power semiconductors can be kept lower with the number of the power semiconductors unchanged. Besides, VDRM is lowed as compared to conventional topology. This renders the reduction of the cost and the increase of the liability.

    摘要： A system and method of improving the power efficiency of a receiver for low duty cycle applications. In one aspect, the receiver includes a low noise amplifier (LNA) that is capable of being enabled in a relatively quick fashion so as to amplify an incoming signal when needed, and then being disabled to set the LNA in a low power consumption mode. In particular, the LNA includes a pair of complimentary devices, and an enable circuit adapted to quickly cause the complimentary devices to conduct substantially the same current. In another aspect, a bias voltage generating apparatus is provided that uses a residual voltage from a prior operation to establish the current bias voltage for the LNA. In particular, the apparatus includes a controller adapted to tune an adjustable capacitor to a capacitance based on a residual voltage applied to a fixed capacitor, and couple the capacitors together to establish the bias voltage.

    摘要： A current drain reducer for an electronic system such as an electronic amplifier operated through controlling selected circuit branches (circuitry of amplifiers 11', 12') said circuit branches each has a control conductivity device located therein which has a control therefore connected to a shutdown signal generator (15'). The potentiometer (16) can have its end terminals in one said circuit branch which may be in a first electronic amplifier circuit (11') and its wiper connected to another said circuit branch which may be in a second electronic amplifier (12'). A sensing circuit (40) for sensing the position of the wiper provides an output signal to the shutdown signal generator (15') in response to sensing a selected position of a potentiometer (16) used therein.

    摘要： A circuit for generating a voltage reference comprises a diodes array (D1) working in conjunction with a switched capacitor amplifier (99) having auto-zero and measure phases so as to create a voltage independent of temperature, a sample and hold circuit (85) which holds the final voltage and buffers for outside use and a feed-back circuit (92) to make the reference voltage insensitive to other circuit components.

    摘要： Telephone circuit using a transconductance switch (11) in a high current line (12) with the voice network (10), and a dial network (34) in a low current line with the control input of the switch to provide dial input signals at the control input and send dial pulse signalling along the high current line through the voice network. The voice network includes a current clamp (13, 14, 15, 16, 17, 18) to stabilize the high current through the switch to the voice network sufficiently quickly to establish the desired waveform during dialling.

    摘要： A plurality of noise limiters (4X and 4Y) have one end connected to an output of a reference voltage generator (1) and another end of each of which is connected to its corresponding load circuit (2X and 2Y). The value of the impedance of the noise limiters (4X and 4Y) is of the same order or higher than the output impedance of the reference voltage generator circuit (1). Preferably noise cancelling means (7) are also provided coupled between the noise limiters (4X and 4Y) and their load circuits (2X and 2Y). Preferably the noise cancelling means are formed by capacitors (7X and7Y) connected across the loads (2X and 2Y).
