摘要： A current and temperature compensated voltage reference circuit uses a power supply voltage as low as 1.3 Volts. A folded-cascode amplifier measures the temperature dependent voltages provided by first and second bias circuits, each including two series-coupled diodes or diode-connected bipolar junction transistors (BJTs), and provides a resulting proportional to absolute temperature (PTAT) current through a cascode-protected output transistor. A voltage reference circuit uses a PTAT current through a resistor to create a PTAT voltage in series with a diode-voltage. The resistor value is adjusted until the sum of these voltages is equal to the bandgap voltage of silicon, providing a temperature compensated voltage reference. The reference circuit is suitable for use with an implantable cardiac rhythm management system having a battery that provides a power supply voltage varying approximately between 1.3 Volts and 3.25 Volts. Cascode-protected current mirrors further improve rejection of such variations in the power supply voltage.
摘要翻译：电流和温度补偿电压参考电路使用低至1.3伏的电源电压。折叠共源共栅放大器测量由第一和第二偏置电路提供的与温度相关的电压，每个电压包括两个串联耦合的二极管或二极管连接的双极结型晶体管（BJT），并提供与绝对温度（PTAT）电流成比例的结果共源共栅保护的输出晶体管。电压参考电路使用通过电阻器的PTAT电流来产生与二极管电压串联的PTAT电压。调整电阻值，直到这些电压之和等于硅的带隙电压，提供温度补偿电压基准。参考电路适用于具有电池的可植入心律管理系统，该电池提供约1.3伏至3.25伏变化的电源电压。串联保护的电流镜进一步改善了对电源电压的这种变化的抑制。

摘要： A voltage regulator in a battery powered device, such as an implantable cardiac defibrillator, provides regulated output voltage for other circuits. When large currents are drawn from the battery, such as during charging of defibrillation output capacitors, switches decouple the regulator from receiving power from the battery and couple the regulator to receive power from a stable boost output voltage generated by a boost converter. The regulator provides a stable regulated output voltage less noisy than the boost output voltage. Controlled switch conductances in the regulator provide operation over a wide range of output load currents.
摘要翻译：电池供电设备中的电压调节器，例如可植入心脏除颤器，为其他电路提供稳压输出电压。当电池从电池中抽出大电流时，例如在除颤输出电容器充电期间，开关将调节器与电池的接收功率分开，并将稳压器耦合到从升压转换器产生的稳定升压输出电压中接收电力。稳压器提供的稳定输出电压比升压输出电压低。调节器中的受控开关电导可在宽范围的输出负载电流下提供工作。
