Series-Terminated Transmitter in 65nm Bulk CMOS
Source-series-terminated (SST) drivers offer the advantage of providing a large range of termination voltages, making them particularly suitable for multi-standard I/Os [1, 2]. Many standards (e.g. [3]) however, call for larger vertical eye openings that require raising the dc supply voltage from the l.OV limit for thinoxide devices in 65nm technology to 1.2 or 1.5V. These requirements are addr...
متن کاملA Low-Voltage, Low-Power, Two-Stage Amplifier for Switched-Capacitor Applications in 90 nm CMOS Process
Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...

متن کاملA CMOS Hybrid Switching Amplitude Modulator for Class-E2 EDGE Polar Transmitters
Abstract A hybrid switching amplitude modulator for class-E2 EDGE polar transmitters is proposed. To achieve both high-efficiency and high-speed, it consists of a wideband buffered linear amplifier as a voltage source and a hysteresis-controlled switching amplifier as a dependent current source. The novel linear amplifier has a high current driving capability of approximately 160mA with a bandw...
متن کاملA Low-Power 2.4-GHz Transmitter/Receiver CMOS IC
A 2.4-GHz CMOS receiver/transmitter incorporates circuit stacking and noninvasive baseband filtering to achieve a high sensitivity with low power dissipation. Using a single 1.6-GHz local oscillator, the transceiver employs two upconversion and downconversion stages while providing on-chip image rejection filtering. Realized in a 0.25m digital CMOS technology, the receiver exhibits a noise figu...
