The Nyquist approach to stability is used in a form suitable for representation on a chart having conventional Smith chart scales. It is shown how the gain and stability of negative conductance reflection amplifiers of the tunnel-diode type can be simultaneously predicted on this chart. The technique described is particularly useful in the practical design of these amplifiers embedded in networ...

An analysis of tnmel-diode low-level detection is presented for the purpose of explaining some of the unusual detection characteristics that occur under certain hias conditions. For example, in the vicinity of its inflection hias point, a tmmel diode exhibits a discriminator-like rectification behavior with two sensitivity peaks. When biased at one of these peaks, the diode is capable of unusua...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

Diode lasers have many benefits, but it is very hard to make diode lasers that have both high spectral purity and high intensity. In this masters thesis a diode laser amplifier with a gain of G=4 is constructed. The amplifier is a double-pass semiconductor laser amplifier and the active region is 100 ~m broad. The amplifier is operated at 793 nm using an external cavity diode laser as master la...

We have demonstrated an all-diode-pumped Yb:YAG chirped pulse amplification laser that produces 100 mJ pulses of 5 ps duration at 100 Hz repetition rate. The compact laser system combines a room-temperature Yb:YAG regenerative amplifier for increased bandwidth and a cryogenically cooled Yb:YAG four-pass amplifier for improved heat dissipation and increased efficiency. The optical efficiency of ...

The reliable operation of SRAM in presence of process variation in sub-100nm devices is largely influenced by periphery circuits, like sense amplifiers, demanding more robust solutions. A new differential sense amplifier for use in standard 6-T SRAM based on gated-diode is proposed and designed. For comparison, three other latch-based sense amplifiers are also designed in 45nm technology. The b...

We report phase-conjugate feedback into a fluorozirconate optical fiber amplifier at infrared wavelengths. By using a semiconductor laser diode at 807 nm, a grating is established in photorefractive BaTiO(3) that, in the ring configuration, provides feedback into the amplifier necessary for laser action. Once written, the grating is self-sustaining, and lasing is observed even after the laser d...

This paper proposes a novel methodology for AMS SoC formal verification based on Hybrid Scheme combined with symbolic computing and LHPN model, FV-HS. The paper is concerned with a class of AMS designs, continuous-time AMS designs i.e., tunnel diode oscillator for research target. Firstly, Labeled Hybrid Petri Net model is established for safety property verification of tunnel diode oscillator,...
