摘要： A regulated charge pump circuit having two-way switching means that switches between a first feedback pathway that provides a precise and stable voltage output and a second feedback pathway that provides a regulated voltage output with low current consumption from the power source. The first feedback pathway maintains a precise voltage output by regulating a pass device that draws current to the voltage output. The second feedback pathway regulates the voltage output by controlling the connection of a clock input to the charge pump. A variable resistor is used to set the regulated level of the voltage output. A digital-to analog converter is formed by using a combination logic circuit to convert a digital input signal to a control signal for the variable resistor.

摘要： A regenerative clock repeater comprises an edge detector and an output driver means to produce the clock signal by recovering its high logical level and low logical level. The output driver means further comprises a pull-up and a pull-down circuitry adapted to receive a pair of control signals. These control signals are generated by the edge detector to sense the rising edge and falling edge of the clock signal. Inside the edge detector, a pair of threshold level detectors detect a high and a low logical level of the clock signal and inputs the results to a combination of logic gates and a latch to keep the locations of the signal markers fixed. These fixed-location of control signals trigger the output driver means to recover the high logical level and the low logical level of said clock signal.

摘要： A sense amplifier circuit for reading the state of memory cells. In one aspect of the invention, the sense amplifier circuit includes a first stage receiving a cell current derived from the memory cell and a reference current derived from a reference cell, and a second stage receiving the cell current and the reference current. A comparator, coupled to the first stage and the second stage, provides an output indicative of the state of the memory cell based on a difference of the voltages provided by the first stage and the second stage, where the state indicated by the comparator is substantially unaffected by capacitive current components provided by transient behavior of the first and second stages.
