    摘要: Digital multilevel memory systems and methods include a charge pump for generating regulated high voltages for various memory operations. The charge pump may include a plurality of pump stages. Aspects of exemplary systems may include charge pumps that performs orderly charging and discharging at low voltage operation conditions. Additional aspects may include features that enable state by state pumping, for example, circuitry that avoids cascaded short circuits among pump stages. Each pump stage may also include circuitry that discharges its nodes, such as via self-discharge through associated pump interconnection(s). Further aspects may also include features that: assist power-up in the various pump stages, double voltage, shift high voltage levels, provide anti-parallel circuit configurations, and/or enable buffering or precharging features, such as self-buffering and self-precharging circuitry.

    摘要: A radio frequency receiver comprising a receiver module, an intermediate frequency (“IF”) module, a synthesizer module and a controller module. The receiver module receives a radio frequency signal and provides a baseband in-phase signal and a baseband quadrature signal eliminates a sideband of the in-phase and quadrature signals to create a first and a second signal, downconverts the first and second signal to a first and a second IF signal, and selects one of the first or second IF signals. The IF module receives the first or second IF signal, performs analog-to-digital conversion on the first or second IF signal, and demodulates the digitally converted. If signal The synthesizer module receives a programmable reference signal, downconverts the reference signal to an IF feedback signal, downconverts the reference signal to a baseband feedback signal provides the IF feedback signal to the IF module, and provides the baseband feedback signal to the receiver module. The controller module samples the digitally converted IF signal and provides the programmable reference signal to the synthesizer module to thereby provide a demodulated output signal.

    摘要: A method to eliminate program deceleration and to enhance the resistance to program disturbance of a non-volatile floating gate memory cell is disclosed. This method eliminates or minimizes the impact of the hole displacement current. This can be done, for example, by increasing the rise time of the high programming voltage applied to the high voltage terminal. Alternatively, the transistor of the non-volatile floating gate memory cell can be turned off until the voltage applied to the high voltage terminal has reached the programming voltage. This can be done, for example by delaying the voltage applied to either the low voltage terminal or to the control gate to turn on the transistor until the voltage at the high voltage terminal has past the ramp up voltage and has reached a level programming voltage.

    摘要: A digital-to-analog converter has a plurality of current cells. Each of the current cells has a level shifter and a current source. The level shifter connects to a first power terminal and a second power terminal to convert a first input signal and a second input signal into a first output signal and a second output signal. The current source has two cascaded MOS transistors connected to the first power terminal in series, a first MOS switch having a gate for receiving the first output signal, and a second MOS switch having a gate for receiving the second output signal. A voltage level of the first power terminal is greater than a voltage level of the second power terminal. When one of the current cells operates, one of the first MOS stitch and the second MOS switch of the current source is turned on and operates in a saturation region.
