Abstract: An improved atomic beam clock apparatus and method are disclosed. The invention substantially reduces errors arising from Rabi pulling and variations in the frequency standard resulting from variations in the amplitude of the microwave signal used to excite the atomic beam. The invention includes a servo loop (22,26,13) that adjusts both the microwave frequency and amplitude. The servo loop measures the output of a beam detector (22) at two pairs of microwave frequencies. The output of the detector at each frequency in each pair of frequencies is measured for two different microwave amplitudes. The amplitude data is used to adjust the microwave power such that the output of the detector is maximized at each pair of frequencies. The amplitude modulation scheme of the present invention may also be applied very advantageously to conventional two point frequency modulation schemes.

Abstract: A receiver is disclosed for a DS/CDMA communication system wherein a symbol is spread with a predetermined spread code to produce a DS/CDMA signal which is transmitted on a radio frequency carrier. The receiver includes an interference canceller for cancelling signals from undesired sources introduced to a signal received from a desired source using a feedback signal. A phase variation canceller is provided for cancelling a phase variation that occurs in an interval between successive symbols of the received signal. Both cancellers are connected in series. A decision circuit compares an input signal from the interference canceller or from the phase variation canceller with a threshold and produces an output representing one of two discrete values depending on whether it is higher or lower than the threshold. A correction circuit derives a correction signal from a signal produced by the interference canceller and applies it to the interference canceller as the feedback signal.

Abstract: A semiconductor circuit integrated with CMOS circuits for receiving a TTL input voltage and generating a large negative and positive voltage swing with respect to p-type or n-type substrate is disclosed. A PMOS negative and positive voltage swing circuit (50) can be integrated with CMOS circuits. The discrete transistor (12; Fig. 1) and the discrete resistor (14; Fig. 1) are replaced by two PMOS transistors (52) and (54). In this circuit the source (56) of the PMOS transistor (52) is connected to a positive voltage (+ V SS) , the gate (58) of the PMOS transistor (52) is connected to the input voltage (V₁)and the drain (60) of the PMOS transistor (52) is connected to the source (62) of the PMOS transistor (54). In order to have the transistor (54) function as an active resistor, its gate (64) is connected to its drain (66) and the drain (66) is connected to a negative voltage (-V DD ). By connecting the gate (64) of the PMOS transistor (54) to its drain (66), the PMOS transistor (54) acts as an active resistor. This invention is based on elimination of the electro-static discharge (ESD) protection circuit which is a requirement for any integrated circuit Eliminating the ESD protection circuit also eliminates the clamping feature of the ESD protection circuit and therefore the circuit can be driven to negative voltages for PMOS circuits and to positive voltages for NMOS circuits. This provides the possibility of connecting the drain of a a P-channel type metal oxide silicon field effect (PMOS) transistor, which is fabricated on a p-type substrate within an n-well, to a voltage below the the substrate voltage. Also, in a n-channel type metal oxide silicon field effect (NMOS) transistor which is fabricated on a n-type substrate within a P-well, the drain can be connected to voltages higher than the substrate voltage. Utilizing this feature of a MOS transistor provides a way to design an integrated circuit which can handle negative voltage swings as well as positive voltage swings.
