A parallel output linear amplifier is provided that includes a transconductance amplifier configured to receive an analog input signal from an input terminal and amplify the analog input signal. The parallel output linear amplifier also includes a first pre-amplifier connected to the transconductance amplifier and operated using a floating drive voltage, and a cascode class AB amplifier connected to the first pre-amplifier and configured to provide an amplified signal to an output terminal. The parallel output linear amplifier further includes a second pre-amplifier configured connected to the transconductance amplifier and operated using the floating drive voltage, and a cascade class AB amplifier connected to the second pre-amplifier and configured to provide an amplified signal to the output terminal.

Abstract:
An integrated circuit includes a NAND string including a string selection transistor SST and a ground selection transistor GST disposed at either end of series-connected memory storage cells MC. Each of the memory storage cells is a memory transistor having a floating gate, and at least one of the string selection transistor SST and the ground selection transistor GST is a memory transistor having a floating gate. The threshold voltage Vth of programmable string selection transistors SST and the ground selection transistor GST is variable and user controllable and need not be established by implantation during manufacture. Each of the programmable string selection transistors SST and the ground selection transistors GST in a memory block may be used to store random data, thus increasing the memory storage capacity of the flash memory device.
Abstract:
A transmitter in a wireless communication system is provided. The transmitter includes a baseband signal processor for detecting an envelope signal, a supply modulator (SM) for producing power to be supplied to a power amplifier using the detected envelope signal, and the power amplifier for receiving voltage from the SM and for amplifying power of a transmit signal. The SM generates a compensation signal corresponding to switching noise generated via switching amplification, and adds the compensation signal and the switching noise. The amplifier of the wireless communication system can produce low switching noise, and the envelope tracking power amplifier can prevent reception degradation due to the noise of the supply modulator.
Abstract:
A method and a supply modulator (SM) are provided for supplying power from a wireless transmitter to a radio frequency (RF) power amplifier. A power control signal input from a modem is received. A reference voltage is determined. An operating mode of the SM is changed by controlling a level of the reference voltage. A voltage is determined based on the level of a reference voltage. When the operating mode of the SM is an ET mode, a first output signal from a linear regulator and a second output signal from a switching regulator are combined to obtain a combined result, and the combined result is output. The first output signal is based on the voltage. When the operating mode of the SM is an APT mode, the voltage based on the reference voltage is output.
