It has been designed a biosensor system using the current mirror circuit. Biosensor system usually implements an amperometric circuit such as a trans-impedance to measure the current value that flows in the solution due to the dissolved oxygen in it. The trans-impedance circuit causing rather high noise, besides that the power supply used must be bipolar; otherwise the measurement range would be narrower. In this paper, a current mirror circuit is used to convert the flowing current in the solution. The current mirror circuit has a lower noise level, besides the power supply needed is just unipolar, and the measurement range much wider. By utilizing this circuit, the biosensor measurement system can be optimized with its achieved advantages

Class E

Starting from the fact that the amplitude of the basic harmonics of the current, flowing through load resistor of the class E power amplifier, is proportional to direct current flowing through the collector battery of the switching transistor, an introduction of a current mirror in emitter circuit of the transistor in whose reference branch is situated a generator of modulating voltage is proposed. It can be easily proven that the total current of this mirror, which is also the direct current of the collector battery, has the waveform of the amplitude modulated signal. This amplitude modulator is verified for performance with pSpace model. .

Abstract In this paper the multiple output current amplifier basic cell is proposed. The triple output current mirror and current follower circuit are described in detail. The cell consists of a split nMOS differential pair and accompanying biasing current sources. It is suitable for low voltage operation and exhibits highly linear DC response. Through cell devices scaling, not only unity, but also any current gains are achievable. As examples, a current amplifier and bandpass biquad section designed in CMOS TSMC 90nm technology are presented. The current amplifier is powered from a 1.2V supply. MOS transistors scaling was chosen to obtain output gains equal to -2, 1 and 2. Simulated real gains are -1.941, 0.966 and 1.932 respectively. The 3dB passband obtained is above 20MHz, while current consumption is independent of input and output currents and is only 7.77μA. The bandpass biquad section utilises the previously presented amplifier, two capacitors and one resistor, and has a Q factor equal to 4 and pole frequency equal to 100 kHz.
