Over the last decade, the field of organic electronics has grown from discrete single unit fabrication to circuit level integration, due to the development of high–performance organic semiconductors (OSCs), large scale fabrication techniques and understanding of operation mechanism. The differential amplifier realized with p-type Pentacene transistors with mobility, 0.5 cm 2/Vs, exhibited a voltage gain of 10 dB in a frequency bandwidth of 1 kHz. The measurement of the transistor characteristics and the amplifier response reported has been carried out with a wafer probing test jig set up. Electrical characteristics of bottom contact TFTs with polymeric PANi-PSS electrodes is superior to those with conventional metal electrodes due to a lower charge injection barrier and resultant lower contact resistance.
The electrodes of the OTFTs were realized using a conductive polymer composite, poyaniline:polystyrene sulphonic acid (PANi-PSS), patterned by a modified Parylene lift-off process.
The OTFTs were fabricated with thermally evaporated Pentacene as the semiconducting layer. In this study, a single stage differential amplifier is demonstrated with flexible OTFTs. The amplifier also employs an excellent D/A converter with multiple S/PDIF inputs, PCM, and DSD capabilities using the ES9018 Reference 32-bit DAC in quad-mono configuration, 8 mono to 2 stereo configuration.Organic thin film transistors (OTFTs) fabricated with non-destructive patterning techniques are the building blocks in realizing flexible electronic interface for sensing applications. For the vinyl enthusiast the CSA100 has RIAA input for moving magnet or high output moving coil cartridges. In this application the tube provides life, headroom and dynamics hard to find in amplifiers relying on solid stage technology only.Ī single chassis made of aluminium alloy to avoid magnetic interference.
If you prefer the warm and nice colored charm of some older tube designs look elsewhere, the CSA100 tube line stage is made for monitoring. The double triode tube runs at high voltage in a setup for maximum linearity, taking care of the voltage amplification only.Ī MOS-FET circuitry delivers the brute force driving the line stage output and feedback circuitry, thus securing a firm handshake between the world of electronic tubes governed by voltage and the current controlled transistor technology. One tube is responsible for the CSA100 line amplification and the efficiency of this single tube layout is astonishing. The CSA100 provides four digital inputs, five analogue inputs and a 100 Watt per channel power amplifier The CSA100 integrated amplifier is a part of the latest work by Copland, aiming to combine the advantages of tubes and transistor amplification using the synectic design concept that previously has made Copland hybrid amplifiers widely acclaimed.
