摘要： A system (1-2) for efficiently transferring harvested vibration energy to a battery (6) includes a piezo harvester (2) generating an AC output voltage (V P (t)) and current (I PZ (t)) and an active rectifier (3) to produce a harvested DC voltage (V hrv ) and current (I hrv) which charge a capacitance (C0). An enable circuit (17) causes a DC-DC converter (4) to be enabled, thereby discharging the capacitance into the converter, when a comparator (A0, A1) of the rectifier which controls switches (S1-S4) thereof detects a direction reversal of the AC output current (I PZ (t)). Another comparator (13) causes the enable circuit (17) to disable the converter (4) when the DC voltage exceeds a threshold (V REF ) thereby causing the capacitance be recharged.

摘要： Charge pump circuitry (1) includes a master charge pump (2) including a voltage multiplier (5) and charge pump (30) which operate to produce a boosted, unregulated voltage (Vunreg), and also includes a slave charge pump (3) including a voltage multiplier (36) and charge pump (50) which operate to produce a boosted control voltage (Vctl) which then is filtered.

摘要： A buck-boost regulation methodology operable, in one embodiment, with a single inductor (L), four-switch (S1 -S4) buck-boost regulator configured for discontinuous conduction mode (DCM). Buck-boost transition switching control by controller (110) IS operable when inductor charge time exceeds a max charge time, and inductor discharge time exceeds a max discharge time, and includes: (a) during charge transition cycles, at the end of the max charge time, if l L is less than a predetermined peak current I L _MAX, switching S2 on (grounding the output side of the inductor) and S4 off, causing lL to increase (a rapid S1 S2 charging current ramp), until l L reaches I L _MAX, and (b) during discharge transition cycles, at the end of the max charge time, if l L is greater than zero, switching S1 off and S3 on (grounding the input side of the inductor), causing l L to increase (a rapid S3S4 l L discharging current ramp), until l L reaches zero.

摘要： An amplifier (20) includes first and second pairs of differentially coupled input transistors. The first current mirror generates a reference current which is mirrored by a second current mirror to produce a mirrored reference current. Current steering circuitry steers the mirrored reference current as a first tail current through the first pair when a common mode voltage associated with a differential input voltage exceeds a first reference voltage. A first portion of the mirrored reference current flows from the first current steering circuitry when the common mode voltage is greater than the first reference voltage to produce a second tail current for the second pair. A second portion of the mirrored reference current is fed back to an output of the first current mirror and summed with the reference current so as to reduce the second portion when the common mode voltage is greater than the first reference voltage.

摘要： Charge pump circuitry (30) compares bottom plate voltages of first (Cl) and second (C2) flying capacitors in a current mode charge pump (IB) to a reference value (VDD-V28) by means of a comparator (20) which drives a flip-flop (22) that generates first (Fl) and second (F2) complementary phase signals.
