摘要： A method and apparatus for generating short electronic pulses using a modified differential trigger that is partly an analogue sinusoidal voltage and partly a selectable, DC voltage. The differential trigger is applied to a differential base band pulse generator having a NAND gate and AND gate. The trigger is applied to both NAND inputs and to one AND input. The NAND output is applied the other AND input. Such a circuit is an OFF state for all input states. However, as the input switches state, the NAND gate delay causes the AND gate to be ON briefly, generating a short pulse. The timing of this pulse can be controlled by varying the constant DC voltage. By using fast switching SiGe CML gates, short pulses with a controllable time off-set can be generated that are suitable for use in automotive radar applications, using only sub-GHz clocks.

摘要： A switch circuit including a first differential amplifier pair providing a portion of an isolation channel, a second differential amplifier pair providing a portion of a transmit channel, and a third differential amplifier pair providing a control bias for selecting either the transmit channel or the isolation channel. The switch circuit provides 35 dB isolation between input and output over a 15 GHz-26 GHz range, yet is only 500 μm by 250 μm in size.

摘要： A receiver circuit including an oscillator, a mixer coupled to the oscillator, a switch coupled to an output of the mixer, and an envelope detector coupled to the oscillator, such that the envelope detector generates a timing signal for actuating the switch based on the envelope of a signal produced by the oscillator. In one exemplary embodiment, the receiver circuit may be used as part of a radar based sensor system.
