I know that Peregrine is designing RF switches in CMOS process.
The performances depend by application. For example for a GSM mobile where the switch requirements for p1db could be up to 38dBm, would be a challenge to do this in CMOS process (at least today). The compet

I'm working on a low power UHF LNA. First I designed single ended the power consumption was around half mW. I had p1db=-15 dBm. Then I designed differential LNA. gain etc. seems similar. Power consumption ~800 mW. However p1db= -30 dBm. I increased tail current until 1.2 mW but only couple dBm imrovements occured. This is an (...)

I have been designing a low Noise Amplifier from 1 to 3 GHz. I am searching for a transistor for my work. Earlier I had used ATF54143 for the design. My goal is to achieve 30K of noise temp throughout the band and its p1db should be +20dBm atleast.
ATF54143 works fine till 2 GHz (~30K from 1 to 2 GHz). The noise temp in a two stage LNA

I need to design an wideband amplfier with the primary characteristic being low distortion (e.g. all 2nd & 3rd order products below 55 - 60 dBc).
The gain is approx. 30 dB, bandwidth (-3 dB) LF - 1,5 GHz, where LF is a sufficiently low frequency (say 5 - 10 MHz).
The amplifier will be used to drive a differential ADC input with power of (...)

p1db -10dBm is high? Maybe you want to say is low.
low gain for LNA you can have turning OFF the LNA Vcc. The insertion loss through the LNA with Vcc OFF it will give you the low gain mode.
Beware that some RF system designs do not require big delta between high gain and low gain mode. A good number for (...)

Just look on minicircuits site or google, and find an Amp w/ p1db ~= 40 and the
rest should take care of itself. But 12V might be too low! Come to think of it
this amp has to almost be 100% efficient from DC to RF power conversion!

I Have noticed a problem regarding the use of LDO regulators in very low noise rf designs. It seems that a LDO regulator from say ROHM or NJRC under normal conditions, (decoupling caps as manufacturers recomendation)give a very low ripple (or possibly a damped oscillation) when placed under load, say 100 - 300 mA. The ripple is around 150mV for a

I could be wrong but in the past I made several coils for loudspeaker

There is another way of making low phase noise oscillators.
The resonator capacitive element consists of a loosely coupled varicap (meaning high Q and low noise) and fixed capacitors.
In reality the fixed capacitors are switched capacitor bank, where the value of the fixed capacitor changes digitally, through diode switches.

There are many trends exhibited by some research groups:
1. multiple or variable voltage supplies (transistor-level)
2. application transformations that infer differentiations at the system level
e.g. the memory subsystem organization and the update rules for these memories. (RTL and system level)
3. adiabatic switching (transistor level)
