  In this paper, we propose a digital control system to automatize the operation of a bidirectional front-end for resonating sensors. Due to the simplicity, the control system is power conservative and compact. The main source of power consumption in the bidirectional front-end is the amplifier used to read-out the sensor. Power can be saved by turning off the amplifier after a few periods of the oscillating signal, which is enough to detect the resonant frequency of the sensor. The concept was initially proved by performing simulations in SPICE by using AMS-350nm CMOS technology model. A prototype was realized with discrete components on a PCB and tested with a power supply of 5V. The reading cycle was fixed at 10kHz and a RLC load has been used as model of a MEMS resonant sensor. The values for the RLC components used for the tests are 100Ω, 270pF, 10mH. The nominal power consumption of the front-end without the support of the sleeping mode is 1.7mW while the sleeping mode with reading one oscillation period reduces the power dissipation to 270μW(15.88% of 1.7mW).

  This paper presents a bidirectional circuit as front-end for piezoelectric ceramic resonators. The front-end both actives and reads the response of the resonator in different directions and the directionality of the front-end is controlled by swapping the supply rails. Experimental results are obtained by measuring on a semi-discrete board prototype. The resonant frequency of the sensor is 110kHz, the bandwidth of the bidirectional front-end is 1kHz - 500kHz which was implemented by using a CD4007UBE IC. Results show that the system provides an easy and effective way to send an activation signal and to read the response of a piezoelectric resonator.

  In this paper we propose a simple and compact way to realize a bi-directional interface to drive resonant sensors. The bi-directional interface can be set to both activate the resonating sensor (activation mode) and to read its response (read-out mode). During the normal operation of the system these two modes are activated alternatively, depend on the state of the control signals. The directionality of this device is decided by swapping the power supply rails. The system has been tested using a RLC load, considered as the model for a resonant sensor. Experimental results of a discrete board prototype show the applicability of the interface for resonant load.

  A generic ultra low-voltage (ULV) CMOS design approach is presented. By applying a floating capacitor to the gate terminal of the enhanced driving transistors, obtained by using a charge injection technique, we may change the ON and OFF currents. The delay in circuits where the enhanced transistors are utilized can be reduced significantly compared to complementary CMOS. The current level of the transistors may be increased for high speed and decreased for low power applications. The design approach may be used to implement ultra low-voltage and high-speed digital logic and Flip-Flops. In addition, the generic technique can be used to implement multiple-valued and analog ultra low-voltage CMOS circuits. For ultra low-voltage digital applications the delay may be reduced to less than 10% compared to static CMOS. The high speed Flip-FLOP presented shows a similar increase in speed compared to conventional Flip-Flops for low supply voltages. For the analog circuit presented the increased current level is used to obtain rail-to-rail operation at higher frequencies than conventional analog circuits.

  In this paper we show how a simple Current-Starved Pseudo Floating-Gate (CSPFG) inverter can be used to realize bi-directional circuits. The direction of the signal through the inverter is reserved (the input becomes output and vise versa) by swapping vdd and gnd, without adding any extra amplifier or circuitry. This is possible because of the symmetry of the CSPFG inverters. We use the bi-directionality property of the inverter to realize a bi-directional CSPFG differentiator/integrator. Typical applications are in filter design and IO ports in ICs. Linearity and AC simulations are presented to show the good properties and versatility suited for Bi-directional analog circuit design.

  In this paper we show how a simple Current-Starved Pseudo Floating-Gate (CSPFG) inverter can be used to realize bi-directional circuits. The direction of the signal through the inverter is reserved (the input becomes output and vise versa) by swapping vdd and gnd, without adding any extra amplifier or circuitry. This is possible because of the symmetry of the CSPFG inverters. We use the bi-directionality property of the inverter to realize a bi-directional CSPFG differentiator/integrator. Typical applications are in filter design and IO ports in ICs. Linearity and AC simulations are presented to show the good properties and versatility suited for Bi-directional analog circuit design.
