Design Note
Precision Ultralow Power High Side Current Sense
Catherine Chang
Introduction
Precision high side measurement of microamp currents
requires a small value sense resistor and a low offset
voltage amplifier. The LTC В®2063 zero-drift amplifier has a
maximum input offset voltage of just 5ВµV and draws just
1.4ВµA making it a great choice for building a complete
ultralow-power precision high side current sense circuit,
as shown in Figure 1. Zero Point
A critical specification for a current sense solution is the
zero point, or equivalent error current at the input for the
output produced when no sense current is present. The zero
point is generally determined by the input offset voltage of
the amplifier divided by RSENSE. The LTC2063вЂ™s low input
offset voltage, of typical 1ВµV, maximum 5ВµV, and low typical
input bias and offset currents of 1-3pA, allow for a zero
point input-referred error current of only 10ВµA (1ВµV/0.1О©)
typically, or 50ВµA (5ВµV/0.1О©) maximum. This low error allows
the sense circuit to maintain its linearity down to the lowest
current in its specified range (100ВµA), without plateauing
due to loss of resolution, as seen in Figure 2. The resulting …

Pocket-Size White Noise Generator for Quickly Testing Circuit
Signal Response
Aaron Schultz and Peter Haak Noise in electrical circuits is typically the enemy. Any self-respecting circuit should
output as little noise as possible. Nevertheless, there are cases where a wellcharacterized source of noise with no other signal is entirely the desired output.
Circuit characterization is such a case.
The outputs of many circuits can be
characterized by sweeping the input
signal across a range of frequencies and
observing the response of the design. Input
sweeps can be composed of discrete input
frequencies or a вЂњswept sine.вЂќ Extremely
low frequency sine waves (below
10Hz) are difficult to produce cleanly.
A processor, DAC, and some complex,
precise filtering can produce relatively
clean sine waves; but, for each frequency
step, the system must settle, making slow
work of sequential full sweeps featuring
many frequencies. Testing fewer discrete
frequencies can be faster, but increases
the risk of skipping over critical frequencies where high Q phenomena reside.
A white noise generator is simpler and
faster than a swept sine wave because …
