  • Patent number: 8896349
    Abstract: A low voltage detector (100) includes a power supply voltage monitor circuit (110) that produces a voltage VSP related to a first a power supply voltage, and a voltage generator (105), which includes a plurality of self-cascode MOSFET (SCM) structures (101-103) in a cascade configuration, that generates a reference voltage Vxm. A voltage comparator (140) outputs an output signal in response to a differential between Vxm and VSP, wherein Vxm and VSP have proportional to absolute temperature behavior (PTAT) over temperature with respect to a second power supply voltage. The output signal changes state when the first power supply voltage equals a trip point of the comparator. Each SCM structure is sized to provide a rate of change with temperature of the PTAT behavior of Vxm that matches a rate of change with temperature of the PTAT behavior of VSP.

  • Patent number: 8830772
    Abstract: A sense amplifier (100) includes first and second inverters (112 and 113). The first inverter has an input terminal (116) and an OUT_B output node and a first transistor (124). The second inverter (113) has an input terminal (115) and an OUT output node and a second transistor (125). The OUT_B output node of the first inverter is coupled to an input terminal of the second inverter, and the OUT node of the second inverter is coupled to an input terminal of the first inverter. The sense amplifier does not use a reference current; therefore, the sense amplifier does not need a reference current generator. The sense amplifier needs only one enable signal to reset a latch (110) of the sense amplifier. When coupled to a non-volatile memory element, voltages at the output nodes are indicative of a logic level of a bit stored in the non-volatile memory element.

  • Publication number: 20130285734
    Abstract: A device (200) includes a circuit (202) and a driver stage (204) therefor. The circuit includes two sub-circuits (231 and 232). The driver stage includes switcher logic (206) that produces signals that control switching on and off of the sub-circuits. The switcher logic also produces other signals in advance of the signals that control the switching of the sub-circuits. The driver stage includes delay compensations circuits (221 and 222), coupled to the switcher logic and to the circuit, that produce timing signals for the switcher logic. The timing signals are closely aligned with moments that a changing voltage at a node between the sub-circuits passes through threshold voltages. The timing signals compensate for all delays of signals through the device such that a period that both sub-circuits are off is minimized, while ensuring that both sub-circuits are not on at a same time.
