This paper presents a brushless DC motor controller with current loop control. The controller applies a complementary PWM modulation scheme to the power MOSFET. The current processor employed by the controller could detect the current flow through the motor windings accurately and convert the current to a voltage input to the error amplifier. The controller has 100% duty cycle high side conduction capability and real four quadrant torque control capability. It is able to implement a tight torque control for a DC brushless motor to satisfy the need of some servo system which calls for high bandwidth and raid dynamic response. 2011 IEEE.

We investigated electro-optic modulator structures to target low drive voltage
high-speed modulation
and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study
the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films
the frequency-voltage-size performances for 2.5GHz
10GHz
40GHz
and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V
1.6V
3.0V and 4.8V
respectively
for the ideal film with r51=730 pm/V at 1550nm wavelength
where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm
0.8 mm
0.4 mm and 0.2 mm
respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation
an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured
which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.

摘要: A novel device of tandem MQW EAMs monolithically integrated with a DFB laser is fabricated by an ultra-low-pressure (22 mbar) selective area growth MOCVD technique. Experimental results exhibit superior device characteristics with low threshold of 19 mA
output light power of 4.5 mW
and over 20 dB extinction ratio when coupled to a single mode fibre. Moreover
over 10 GHz modulation bandwidth is developed with a driving voltage of 2 V. Using this sinusoidal voltage driven integrated device
10 GHz repetition rate pulse with an actual width of 13.7 ps without any compression elements is obtained.
