Passive, Discrete, DC Coupled, Open Loop IV Converters

Ruschkowski got inspired by his friend Erno Borbely (who should not need any introduction) to design a discrete I/V converter for his newest DAC. This converter uses a low-value resistor to convert the DAC output current to a low level signal. The signal is then amplified with an open loop discrete low noise amplifier to regular source levels. Unbalanced and balanced output implementations are shown with performance measurements. As part of the setup, a high performance shunt regulator is also presented.
