The Class-E power amplifier is widely used due to its high efficiency, resulting from switching at zero voltage and zero slope of the switch voltage. In this paper, we extend general analytical solutions for the Class-E power amplifier to the ideal single-ended Variable-Voltage Class-E (Class-Evv) power amplifier that switches at zero slope but not necessarily at zero voltage. The theory is ver...

We present measurements of the power noise due to optical amplification in a Nd:YAG free-space traveling-wave amplifier as the amplifier transitions from the linear regime into the heavily saturated regime. The quantum noise behavior is demonstrated by saturating the gain of a 100-W class zigzag slab amplifier with a high-power beam and measuring the power noise detected by a single-spatial-mod...

A 2.4-GHz single-stage CMOS low noise amplifier (LNA) structure with ultra low power consumption is proposed. A current reuse technique is used to decrease power dissipation with increasing amplifier transconductance for the LNA. Thus, the same amplifier transconductance for the LNA will be achieved at decreased power dissipation. Also, due to the use of an inverter-type amplifier which has a s...

We present a high power, single-frequency fiber amplifier based on master oscillator power amplification (MOPA) chains in all-fiber configuration. A 1.5 meter long highly doped Yb fiber with absorption coefficient as high as 16 dB/m at the 975 nm wavelength is used for the main power amplifier, no special assistant stimulated Brillouin scattering (SBS) suppression approach is employed.
