Cmos amplifier design jobs
This project involves using a series of piezo-electric vibration sensors on a drum surface to detect a drumbeat. The required parameters will be strength of the beat (amplitude), frequency of the beat (eg. beats per minute/hour) and location of the drumbeat. This may require an instrumentation amplifier for smaller vibrations. The sensors, ADC converter and instrumentation amplifier will need to be stuck to a flat sheet that can be placed on top of the drum. The analogue signal will need to be converted to a digital signal and wirelessly transmitted to a computer and mobile device where an output can be read. This may also involve simple visualisation of the output as well. Please see the attached document for a basic proposed visualisation of how the system could...

Hello, We are looking for someone with your skills for the project. This is about a power amplifier with such characteristics : Input Signal: Sinusoidal AM Frequency : 13.56MHz Power : 12.5mW (11dbm) Vpp : 3.3V Impedance : 50 ohm Connector SMA Output Signal : Same signal with as little distortion as possible, no frequency shift Power output : 20W-25W Impedance : 50 ohm Connector SMA We need Circuit Design, PCB layout and BOM. Are you interrested and available for such work ? What would be your price ? Regards
We need someone to design a pre-amplifier (not a LNA, we need a current amplifier) circuit, ONLY the circuit (not the PCB) for those characteristics : Input Signal: Sinusoidal AM Frequency between 12 and 14 MHz Power : 12.5mW (11dbm) Vpp : arround 3.3Vpp (3Vpp-3.5Vpp) Impedance : 50 ohm Output Signal : Same signal with as little distortion as possible, no frequency shift Vpp : same as the entry as possible Power output : 16dbm - 40mW Impedance : 50 ohm Ideally if you could use 2N3904/2N3906 or 2N2222A/2N2907 as for the transistor (We already have those in stock) it would be great but you can use whatever you need. This is an URGENT project.

...tone bursts at a pulse repetition frequency until a desired number of tone bursts had been generated (Figure 1B). Ultrasound tone bursts were generated by trains of square waves (0.2 µsec) with variable amplitudes (Table S1) using an Agilent 33220A function generator. To produce final plate voltages delivered to transducers, square waves were further amplified (50 dB gain) using an ENI 240L RF amplifier. Square waves were delivered between 0.44–0.67 MHz depending on the acoustic frequency desired, while the number of square waves driving each US tone burst equaled the number of acoustic cycles desired for a given US tone burst. Each US tone burst (pulse) contained between 1 and 50,000 acoustic cycles depending on the LILFU waveform generated. US tone bursts (Figure 1B...

We are looking for someone to optimize a prototype we have for a device that provides audio feedback when a sensor is triggered. Our current prototype uses a RaspberryPi micro-controller and voice amplifier to play audio from a user-configured microSD card when a signal is received from either an Ultrasonic sensor or an infrared sensor (currently using a combination of the two sensors). Looking for someone to bypass RPi and optimize with process specific micro-controllers. Looking for someone to optimize battery life for up to 3 months without charging as well as have the option to run continuously on solar panel (while keeping battery within an approximately 6x10x10cm cubic area).
