A sensing amplifier for a memory cell comprises a selection stage that outputs one of a reference current and a memory cell current during a first period and the other of the reference current and the memory cell current during a second period. The first period and the second period are non-overlapping. An input stage generates a first current based on the one of the reference current and the memory cell current during the first period and generates a second current based on the other of the reference current and the memory cell current during the second period. A sensing stage senses a first value based on the first current and stores the first value during the first period, senses a second value based on the second current during the second period and compares the first value to the second value.

A system includes an input that receives a control signal and a program module that initializes a nonvolatile multilevel memory cell based on the control signal. The program module initializes the nonvolatile multilevel memory cell by programming the nonvolatile multilevel memory cell to one of S states of the nonvolatile multilevel memory cell, where S is an integer greater than 1. The one of the S states is different than a lowest one of the S states.

A low leakage power management system is provided. An external voltage domain is selectively coupled to the internal voltage domain of an integrated circuit according to demand for the functions provided by the integrated circuit. An external voltage Vis connected to the internal supply voltage plane of the integrated circuit when the integrated circuit is active. The external supply voltage Vis disconnected from the integrated circuit chip during idle periods. A plurality of switch cells may be provided for connecting the external voltage Vto the integrated circuit. A multi-step sequence is provided for connecting the external supply voltage Vto the chip's internal supply voltage plane to prevent excessive current from flowing through any individual switch cell.

The disclosure can provide methods and systems for autocalibrating a transceiver. The method can include upconverting a bandpass input signal by mixing the bandpass input signal with a first local oscillator signal to form an initial transmitter signal. The initial transmitter signal can be looped back to a receiver and downconverted with a second local oscillator signal having a frequency that is different from the first local oscillator to form an intermediate frequency signal. At least one of a gain and a phase of the transmitter can be adjusted based on a transmitter image sideband of the intermediate frequency signal to generate a calibrated transmitter signal having minimized transmitter image sideband.

A level shifter includes a level shifter module that receives a first input signal having high and low states and at least one voltage supply signal, and that generates a latch control signal based on the high and low states of the first input signal. A latch module receives the latch control signal, a data input signal, and the at least one voltage supply signal. The latch module selectively stores data associated with the data input signal based on the latch control signal. The latch module selectively changes the at least one voltage supply signal from a first level to a second level and outputs the data according to the second level based on the latch control signal.
