... Tight current gain matching (3% max mismatch) and high current gain (100 min), over a wide range of collector cur- rent, makes the MAT03 an excellent choice for current mirrors. A low value of bulk resistance (typically 0.3 Ω) also makes the MAT03 an ideal component for applications requiring accurate logarithmic conformance ...

... The 5 kΩ collector resistors noise contribution is insignificant compared to the volt- age noise of the MAT03. Since noise in the signal path is referred back to the input, this voltage noise is attenuated by the gain of the circuit. Consequently, the noise contribution of the col- lector load resistors is only 0.048 nV/√ ...

... LOW NOISE MICROPHONE PREAMPLIFIER Figure 4 shows a microphone preamplifier that consists of a MAT03 and a low noise op amp. The input stage operates at a relatively high quiescent current per side, which reduces the MAT03 transistor’s voltage noise. The 1/ƒ corner is less than 1 Hz ...

... The circuit of Figure digitally programmable current pump. The current pump incorporates a DAC08, and a fast Wilson current source using the MAT03. Examining Figure 7, the DAC08 is set for 2 mA full-scale range so that bipolar cur- rent operation of ± achieved. The Wilson current mirror maintains linearity within the LSB range of the 8-bit DAC08 (± ...
