Using the TDA7052A audio amplifier to generate a five octave, linear in pitch voltage-controlled oscillator (VCO).
Abstract: In the past decade, detection of THz radiation by plasma-wave-assisted mixing in antenna-coupled field-effect transistors (TeraFETs)—implemented in various semiconductor material systems (Si ...
Abstract: This paper investigates the front-end hardware circuit of an Arbitrary Waveform Generator (AWG). To reduce the demand for ADC sampling rates, a spectrum signal stitching system was ...
