    I am looking for a skilled Analog Electrical engineer to modify a linear amplifier using op-amp and BJT transistor technology. The amplifier should have a low gain of less than 10 and a low output impedance of less than 100 ohms. Additionally, the preferred power supply voltage is 24V. The ideal candidate should have experience in designing linear amplifiers and be familiar with op-amp and BJT transistor technology. A strong background in analog circuit design and analysis(LTSpice or PSpice) is also preferred.
